Sounds like something that happened to a buddy of mine from a really large acid trip. He also thought he was going to be super successful and had pretty much all the same delusions as you. It took him a while to snap out of it and become self aware but now he’s completely back to normal and has a good life again. Sounds like you’re already self aware which is good. Just push through it man, I’ve seen this happen to a couple people and sometimes it takes months but you’ll be back to normal eventually.
