New Struggles

"I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world."

-John 16:33-ο»Ώ




Dear friends,

This was a hard post to write. I had 2 rough appointments recently…both just a few days apart—one with my primary care physician and the other with my neuromuscular neurologist. I broke down and cried a lot at each of them. 😭 It doesn’t seem like I’m improving with time, so my PCP recommended that I be seen at the center for complex diseases in Seattle, but we found out they don’t take insurance (in addition, the very specialized autonomic neurologist also in Seattle that one of my other doctors referred me to doesn't take insurance either).. πŸ˜”

My doctor always shows such compassion (very thankful for him!!), and he explained that something needs to be done because I’m continuing to struggle even more. I’m starting to experience brain fog which has been difficult. If I’m searching something online, I suddenly forget what I was looking for. More than a few times now, I said something to my family, and they told me I already brought “that” up. πŸ₯Ί

My elbow joints have been so achy and painful lately. We don’t know if this is related to a slowly developing issue—the rheumatologist said sometimes symptoms can gradually develop before it becomes a full-on autoimmune disorder, and she said to watch and pay attention to any new symptoms.. I still have the second opinion with a different rheumatologist in late June..

On top of all this, I began experiencing terrible muscle spasms in my low back muscles which wake me up in the morning. πŸ˜” The neurologist said this is called “spasticity” and is a muscle control disorder characterized by tight or stiff muscles and an inability to control those muscles. I’m not able to get quality rest at night due to these muscle spasms as well as the frequent central apnea episodes that occur (detailed in a previous blog post). 😞

My nystagmus has also been simply horrible and always occurs now with mild activity (it used to just happen with sepsis or when a “mito crash” was brewing). If you are curious what nystagmus is: it’s like seeing the world through a very shaky camera lens, and your eyeballs oscillate back and forth horizontally. The brain fog and nystagmus is happening because my brain is not getting enough energy due to the mitochondrial depletion. The pain in my legs has also been very hard to deal with (especially at night), and this, too, is caused by my nerves/muscles not getting sufficient energy. 😒

We’re trying to manage these difficult symptoms with medications and all sorts of supplements, but it’s still so rough. 😭

My neurologist said degeneration is occurring. Had a difficult discussion with him about what to do. I already receive a 4 hour infusion 5 days a week, but he wants me to receive another half a liter of IV dextrose and run it quickly over 30 minutes.. He hoped to add a specific amino acid to each bag, but we found out my infusion company can't supply it or even order it which was so disappointing.

Very weary and exhausted fighting this mitochondrial depletion syndrome day after day with no reprieve. πŸ₯Ί This July will mark 15 years of fighting mito and all my other diagnoses. Please pray for supernatural endurance to keep persevering. Pray that I will lean on the Lord, draw strength from him, and not lose heart. I know this is just a rough season I’m in which will hopefully pass, but it’s hard while in the thick of it. Trying to remember that the Lord carried me through 15 long years, and he will do the same for the next 15.. ❀️

This passage from 2 Corinthians comes to mind, and I really resonate with it:

“For we do not want you to be unaware, brothers, of the affliction we experienced in Asia. For we were so
utterly burdened beyond our strength that we despaired of life itself. Indeed, we felt that we had received the sentence of death. But that was to make us rely not on ourselves but on God who raises the dead. He delivered us from such a deadly peril, and he will deliver us. On him we have set our hope that he will deliver us again.” -2 Corinthians 1:8-10

So thankful Jesus is with me in the midst of all this suffering. Could you please also pray hard that the Undiagnosed Diseases Network through Harvard will accept my complex case and work to find the gene mutation responsible for this worsening mitochondrial depletion? If a mutation is found, then I could potentially be enrolled in clinical trials! The UDN has a 40% acceptance rate, and I should hear the final decision in 2-3 months..

Thank you so much for your continued love and prayers, friends. πŸ’š

Dear friends, Thank you so much for praying for me when I had that bad reaction to the autoimmune medication last month. I’m so incredibly blessed by your love and support. ❀️ I saw rheumatology recently, and instead of trying to prevent actual autoimmune disease from starting, they want to just monitor without any medication therapy. In other words, they want to see if more symptoms like fevers or rashes will appear (besides the joint pain that I already experience).. The medicine I did try (which worsened my mitochondrial symptoms) is actually the “safest” out there, and the other treatments for autoimmune disorders are much harder on the body—the team doesn’t think I’ll tolerate those well.. It’s difficult for them to know if all the bad antibodies that have been found in my blood will cause “actual” disease, and only time will tell.. So the plan is to just monitor and follow up with them in February. I wanted to see if my body could recover from this setback without having my IV fluids switched to a higher dextrose percentage. But by the last week of October (week 3 of this mitochondrial flare), the muscle weakness and increased pain all over was sadly still persisting, so I told my doctor. He sent in a new IV fluids order with the higher dextrose, and I’ve been receiving it for about 2 weeks now. I have definitely noticed an improvement in the muscle weakness which has been a huge blessing from the Lord. It was such a gift to feel well enough to go to a friend’s wedding reception at my church last week. πŸ₯Ή My cup was filled because I haven’t been able to see so many church friends in years! Regarding the piece of plaque that traveled to a small artery in my retina, I just had the carotid duplex scan completed last Tuesday to see if there’s any narrowing in the neck arteries. I also have the heart echocardiogram scheduled for tomorrow. My biggest, ongoing struggle has been my sleep. I’ve sadly been in a “catch 22” situation for many months now. I mentioned before that I was started on a new and safer pain medication this year. A rare side effect is insomnia, and it’s simply horrible. Night after night, every single day, I’m not able to fall asleep until after 4-6 AM. 😒 Believe me, I’ve tried every type of trick…from different sleep medications that my sleep specialist has prescribed, to all sorts of sleep supplements, praying, listening to worship music or white noise, stopping caffeine intake, etc. Nothing helps. The thing is, if I didn’t take this “new” pain medication, the pain from Mitochondrial DNA Depletion Syndrome is difficult to manage and it’s like an 8-9 on the pain scale. So then I’m up through the night, in horrible pain, and not able to sleep. But when I do take this medication, the pain is manageable, and it’s much safer to be on... Yet, I can’t sleep well while on it... Catch 22. I don’t know what to do, and it’s hard not to feel alone in this struggle. I’m so thankful to God that my health in other areas has been pretty stable.. In fact, this month (November) marks ONE WHOLE YEAR since I was last admitted to the hospital! Isn’t that soo amazing? Aside from these occasional mitochondrial flares/crashes (which happened in December, May, and October), I’ve been doing incredibly well, now that the neck weakness has resolved. But, this sleep struggle persists day after day.. I would love to be able to attend my church’s morning service in person or do many other activities in the morning. 😞 But I’m super exhausted. So many times, I ask God, “How do I go on and keep doing this every single night?” One thing I’ve learned is that God’s grace is truly sufficient for each day. He is the one who supplies me with the energy and grace to keep enduring. It’s hard, and I don’t know how long this sleep trial will last.. But, as Thanksgiving draws near, I’m reminded that I do have so much to be thankful for. Some of the biggest things: being physically able to help babysit my 4-month old foster nephew, shopping at the grocery store, having hand strength to design new note cards like the ones shown here, no longer experiencing neck weakness, and much more. The verse from Zephaniah I recently hand lettered above has been so encouraging lately. God is right by my side; he is mighty to save and will keep helping me through anything that I face. ❀️ ο»Ώ

Dear friends, At the beginning of October, I started taking a new medication for the autoimmune disease. I thought I was tolerating it just fine, but after several days passed, I began experiencing nausea, loss of appetite, weakness all over, and increased pain. πŸ™ It’s like I’m experiencing another “mito crash.” I found out that this specific lupus medication affects mitochondria. That is, it causes an overproduction of reactive oxygen species (ROS). This, in turn, causes cell damage and oxidative stress. I sure wish the rheumatologists would have known about this before prescribing. But I have to remember that Mitochondrial DNA Depletion Syndrome is rare, and they’re not “mito experts.” Anyways, the last time I felt like this was back in May.. I’m so grateful to God that I haven’t needed to be hospitalized from this, but at the same time, I’m also sad that this happened at all, especially because I had such a nice stretch of stable health. I’d really appreciate your prayers, that this muscle weakness can resolve soon, and that this increased pain all over will get back to my baseline. Every time I have a “mito crash,” it feels like I’m fighting the flu which always sucks. The pain has been hard to bear. And whenever I’m in the thick of it, it’s difficult to remember that this too will eventually pass. 😒 Pray that I will endure and follow Jesus’ example like this passage from Hebrews 12:1-2– “Let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross...” Thank you all so much for praying for me. ❀️
