A lot of my friends also have or had similar issues to me from doing the same stuff. I went through a period of doing a lot of acid in my teens for a couple of years along with 'shrooms, ket, mdma, weed and basically anything else I could get my hands on and eventually went on a really, really rough trip and have been struggling to get back to "normal" ever since. It was basically just a case of overindulging at a young age and I really regret it despite having a lot of fun.
Yeah, I just wish I'd been a bit more sensible with it. It was also around the time that more and more people started finding really unpleasant stuff online which, thankfully, I avoided for the most part as one of the few times I ended up taking any of it I had an absolute nightmare with that DXM stuff they sometimes put in cough medicine in the US. I got lost on the edge of the countryside on my own, at night and with no credit on my phone feeling somewhere between a speed comedown and a k-hole whilst having such intense itching all over my body and nausea that I just ended up lying on the ground and scratching my arms raw until some mates from the party I'd got lost on the way to happened to find me on the side of the road.
