Well I was already diagnosed as mentally ill with the ADHD lol, when I was in PHP I just told the program’s psychiatrist I take vyvanse, and he could see my medical records to verify so he filled my script along with the invega shots. I got all of them in my arm. I had been taking vyvanse for over a year before my psychotic episode, and before that I was on adderall for a year so they weren’t really worried about me abusing them, and since I was taking an antipsychotic with it they weren’t concerned about psychosis either.
Months 5-8 I noticed it working only occasionally, my usual signs that it’s working were the physical symptoms like heart rate. My psychiatrist actually raised my dose to 70mg, the largest dose allowed to be prescribed and I still didn’t feel much, so it was lowered back down to 50mg. I was prescribed bupropion 3 months ago as well, I’m not sure if this contributed to me feeling vyvanse again though.
My job doesn’t deal with computers or math at all, it’s all hands on but requires me to focus on one task for over an hour at a time (was really hard for me before without feeling like I was being tortured mentally), and doing multiple things at once while keeping track of the timing of everything (helps me not feel overwhelmed with the amount of things I’m doing).
I’ve always done a lot of research on things though, and even though I may not know how to code, I’m able to do complex things on the computer if I find instructions, learned from playing Minecraft as a child lol.
I’m autistic as well, wasn’t diagnosed until I was an adult and only after my ADHD diagnosis though. I can’t speak for dyslexia since I don’t have it, but I know it’s not curable and you aren’t dumb

your brain just works differently. When you’re able to feel vyvanse again though, please don’t abuse it. I’ve been there too, taking an extra dose for the extra boost, taking extra just to be better at video games, or mixing it with weed. It’s just not worth it in the long run. It feels great in the moment, but the crashes just become more severe because you’re pushing your mind and body to their limits. We all know that taking too much can cause psychosis, but the withdrawals can also cause psychosis! I feel more stable just taking it on weekdays, you can’t fully rely on the meds you have to change your habits and mindset as well.
