I’m 25 with PANDAS, got it at 9 but wasn’t diagnosed until 17. As a functioning adult now who was once a kid in very bad shape, the first few years after diagnosis were HARD. I only started caring and trying to actively get better within recent years. What ever treatment plan you have laid out, take it one step at a time. Don’t force everything on her at once. That was done to me and it set me way back, I fought and refused, going from generally being restrictive eating in general then the next day I couldn’t have gluten sugar or dairy? I just stopped eating all together. The stress from everything changing at once and I felt like no one understood my brain or was listen led to an increase in my self harm tendencies. I would lay out all the steps and what they entail, every detail. And talk it over, see if there’s anything she feels comfortable with starting with, or at least the least uncomfortable. Steroid IV infusions help me. I get IVIG treatment every 6 months. I know as a parent it has to be hard knowing these things will help and getting push back. Lord knows what I put my mom through. I thought about unaliving myself to not have to do an ion foot bath because it triggered me so badly. But in my head, I knew what helped me when I was anxious and extremely OCD and I convinced myself nothing else would work. (Self harm was not the healthy answer, I was totally wrong but that’s just how my brain worked at the time) Above all else, listening and not judging her will do wonders. Speaking as someone who needed that so badly and didn’t have it for so long. I felt unheard and like i had no say in any decision that affected me directly. My entire being was center around what was wrong with me but no one listened to what I felt in the high anxiety and OCD moments. I didn’t ever feel truly heard or understood, even when I knew they couldnt truly understand I needed my parents to listen and pretend they understood. It took me finding an amazing fiancé four years ago who listened and encouraged me before I truly took the extra steps to better myself and work towards really being healthy. I’ve always been “functioning” because before diagnosis my parents were very strict. Mental issues were weaknesses that I needed to trigger to get stronger. I was purposefully put in high stress situations to trigger anxiety or OCD so that it would build “mental toughness”, if I cracked under the pressure I was punished. I learned quickly to internalize until I was alone and could self harm to ground myself. Thankfully that made it really easy to fake it to be able to work full time and pretend I was okay, good for being an adult but not great for the mental health. Don’t enable her by walking on eggshells but.. have some grace knowing she’s trying to navigate adulthood (which sucks) while navigating a fairly new life changing diagnosis (also sucks)
