Dissociating for a month now

Last month I did a LOT of speed and Adderall mixed together. I was drunk but the amount was insanely high and I did it all over a period of about 6 hours. Probably did upwards of half a gram. I stayed up for 36 hours, vomited, and had hot flashes and blurred vision - the whole nine yards. That was my first time doing stimulants and my last. I had no tolerance.

Ever since then, I've been feeling dissociated. I've never had problems with dissociation before so this is new to me. I went to a family doctor who said I would be fine in a couple of weeks, I went to the ER after a panic attack and they said I should be fine. I went to an ophthalmologist to see if my eyes were fucked up (because of the weird dissociation vision) and she said I would be fine. How long could something like this take to go away? Am I screwed? It's been going on for exactly a month today which is why I'm making this post. I'm scared and any help or advice would be appreciated.
