Mental: Severe anxiety (true root of all my problems) and depression, body dysmorphia which has caused eating disorders in my past and excessive exercise, dissociation (both derealization and depersonalization), probably others. SSRIs also destroyed me. It killed my libido which is still non-existent seven months off it. This has actually helped with the eating disorders since I don't fear a little gain weight as much as I used to. I really would get too thin at times, but I'm at a healthy weight currently. I still crave a little validation though, so also not letting myself go. Still, I prefer the libido which was insanely high before and made me feel good. They also caused anhedonia as well, which is miserable. But the worst thing it's done to me is akathisia, which I've continued to experience for seven months now and it's one of the biggest reasons I want to die. Truly indescribable torture. I take kratom for it. It helps, but still not 100%, and it'll cause withdrawals down the line which will also worsen the akathisia.
Neurological: Once again, aka-freaking-thisia, chronic nauseating migraines, partial seizures, tinnitus, etc.
Physical: Rheumatoid arthritis, and endometriosis that has progressed and now have to deal with everyday, and not just around the time of my period. The RA prevents me from being able to exercise like I used to, which although was excessive, it has caused my mental health to deteriorate even further because it was the one thing that helped my depression the most.
Basically, I'm always in pain or profoundly uncomfortable, both mentally and physically. I feel generally ill at least once a day. But you wouldn't know it by looking at me, unless I'm limping from the RA, which doesn't happen 24/7 and most people don't see.
