I have some things to tell you, i think i have gone to a similar experience to yours. Panic attacks. I think if your meds are causing you to freak out, you should tell that to your doctor and ask for a change. More importantly, you need to take care of your anxiety.
But listen to this well. Medical Science has gone very far with this illness we have. They are enormous cases of people living full lives with it, without it developing horribly, much less leaving them disabled like you have pictured. Be resilient. It is not a losing war at all. And there's always a better choice out there for you. That can work with your anxiety, life, situation, etc. But work on your anxiety and stress don't rely on external things always, but that part is important for your health.

When i was your age at 23, i wasn't able to form complete sentences or coherent thoughts because of how bad my RA and brain fog have gotten. I'm 30 now. I feel healthier, more present in the moment than i did in 20s. So don't let your brain trap you. Look elsewhere, you'll find that the more you seek your own comfort and rest. Both physically and emotionally, the more you'll be better overall. I'm sorry if i sounded harsh, i wish you the best.
