Am I cooked

I’m 20F and I got diagnosed about a year ago. I went to a therapist at my university for severe depression and ended up getting diagnosed with ADHD. I had somewhat suspected it, I have a hard time paying attention and have always been a fidgety person and have difficulty regulating my emotions, along with extreme time blindness, but never actually knew I had it, and even now I still doubt. Quick background on me that will be important - I have always been a small and skinny person, never had an unhealthy relationship with food or anything wrong medically, just my dna I guess.

Anyways, I started on Concerta and was on it for about 2-3 months slowly increasing dosage. It destroyed me ~ I barely ate at all and only ever felt hungry at night, my heart rate was going crazy, and I felt awful. I dropped to a unhealthy weight and had to stop taking it. I did notice it helped with emotional regulation if anything, but I found myself somehow feeling even lazier than usual and the cons heavily outweighed the pros. My psychiatrist then put me on Wellbutrin, and though I had very little to no symptoms on Wellbutrin, I wasn’t noticing any change in my behaviors. A little over a month ago my psychiatrist put me on Vyvanse. The first week I felt relatively fine, I could eat fine, and I was definitely more talkative than usual. That has since subsided and after a month of being on it I’m noticing a decreased appetite (though I still get really hungry, I get full after a few bites of anything), a fast heart rate for hours, and shortness of breath in the evenings. I have found that mentally I feel calmer (hard to explain, but my brain is quiet) but my executive functioning is still awful (messy room, bad personal hygiene, etc.) I wouldn’t say it’s done much else, except for I spend a lot more time on my hyperfixations than my school work and my health anxiety has increased.

This leads me to my question, does it get any better? It seems like all ADHD meds are appetite suppressants, which for someone like me is dangerous. I hate the fast heart rate, it makes me scared to do active activities since I don’t want it getting any faster. I feel like the easy explanation is that I don’t really have adhd and that’s why my body reacts so much. Im not sure what to do, I’m more or less alone in this journey and scared of my health getting worse, but vyvanse has helped me emotionally and helps me stay focused, but I’m still very fidgety, and the health effects make me anxious. Should I just stop trying to make meds work?
