More difficult news..

Dear friends,


I’d really appreciate your continued prayers. 🥺 Thank you for being on this journey with me through the good and bad. ❤️

Last year, I had a sleep study where I shared that I was diagnosed with moderate Central Sleep-Disordered Breathing (central apnea happens when the brain doesn’t tell your body to initiate breaths). It was noted that I stopped breathing about 17 times per hour. Well, my neurologist wanted me to get yet another sleep study last month to make sure this neck weakness hasn’t caused worsening apnea. And I’m sad to share that the results were much worse than last year’s. :( I thought last year was bad, but this latest study shows that I stopped breathing more than 40 times per hour (almost 400 times total through the whole night). 🥺 This was hard to hear and also such a reminder that God is the one who gives us “the breath of life” (Genesis 2:7) every minute. It’s by his mercy that we wake up to each new day. ☀️


What makes my case complex is that my esophageal sphincter has been affected by the mitochondrial disorder—it’s weak, so when air from a sleep machine is pushed down into my lungs, bad throat gurgling happens which keeps me up at night because my esophageal sphincter can’t close all the way like it should. :(


My appointment with the rheumatologist was yesterday, and I wish I could say she gave a concrete diagnosis of what’s been happening these last several months…but that wasn’t the case. 🥺 I have to get more specific labs done. She also ordered x-rays of my hands and feet to check for possible spots of rheumatoid arthritis or calcinosis.


The doctor said sometimes a new condition happens gradually, and it’s a wait-and-see type of situation. 😥 If these additional tests and labs still don’t give a clear cut answer, I’m so glad I have a second opinion with another rheumatologist at the end of June. This one sounds especially good because he’s a DO (doctor of osteopathic medicine) and offers a whole-body approach regarding treatment. Could you please pray something can be done soon as my quality of life continues to be rough, and these latest symptoms have been going on for half a year now. :’( Hard to believe October was 6 months ago! All this time, I’ve just been waiting..


I did ask my PCP at one of my appointments if he ever orders treatment for something even without a definite diagnosis, and he said “yes” which was encouraging to hear. His family leave is almost over, so I see him again soon.


Just finished a virtual follow-up with another one of my amazing doctors this afternoon. 💜 She knows a very specialized neurologist in Washington who has his own private practice. She wants me to see him and hopes he’ll be able to connect all the dots and see the bigger picture. So blessed by all of my many doctors who try their best to help me! 🥲


I started the process in applying to the Undiagnosed Diseases program through Harvard (it got pretty delayed because of my 2 mitochondrial crashes in November and December). My application has been assigned to the Seattle clinical site. Please pray that the doctors who review my case will be able to accept me as a patient and find the genetic defect causing my mitochondrial depletion. The UDN acceptance rate is about 40%..


I saw this quote recently by Martin Luther and just had to hand letter it (so thankful for one of my neurologists who increased the anti-seizure medication which has been helping to decrease my hand tremors). ❤️ This statement by Martin Luther is such a beautiful reminder. All that’s happened lately has been the hardest trial, but I’m praying that I will persevere and bear this cross daily to bring honor to the Lord. I know my life is in his loving hands.


I’m thankful for God’s promises in Romans 8:28–“And we know that for those who love God all things work together for good, for those who are called according to his purpose.” ✨

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. 🥹 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. ❤️

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. 🙁 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. ❤️
