A few months ago, I got my hands on some pure amphetamine sulfate and used it for about a week straight everyday till it ran out. I slept almost every night, got my 7/8 hours, except for skipping one night of sleep
During this night, I also danced a lot, it was pretty hot where I live so I sweated a lot
My question is, would this qualify as hyperthermia, and if so, have I damaged my brain to a considerable extent?
My sleep cycle has been pretty messed since, but I could attribute it to a number of factors, but I do feel anhedonic, leading me to believe that there may have been neurotoxicity to some extent due to the hyperthermia

Am I being overly paranoid for nothing, or is there a chance I could've damaged my brain?
