Hey man,
I just wanted to say I know what you're going through dude. The first time I took lsd (close to a month ago) I had a both a great experience and a horrible trip (played out an 'acid nightmare') at the same time. I had distorted perception, was terrified of going mentally insane, disconnected from reality, not knowing who I was.. And all of this while standing next to my parents and brothers room as they were asleep. I came close to ending my life then and there and almost called the hospital. Luckily I gripped sanity so tightly I didn't and ended up going to see a couple mates who I had been tripping with earlier.
I wanted to let you know that you know that you're not alone man. I'm 19 and have also told my mum everything, talked to my friends about it, written about it and seen a doctor (who was a psychiatrist for 8 years - and who, it turns out, had taken lsd 13 times and shared his experiences with me) said that I have opened parts of my mind which were previously unopened or relatively untouched - and that exercise, good diet and socialising will fix up. He also gave me some Olanzapine for emergency use and told me he preferred if I didn't take it (which I haven't done and do not plan to).
My symptoms are: Sometimes I become anxious for no apparent reason and tend to view the world differently than I had before. It's not horrifying or life-changing, I still function as I did before the trip, it just becomes uncomfortable to think about at times (hence the need for exercise - I'm going to the gym 8 hours a week). I still feel like I need more time to fully 'recover' from the trip and to stop thinking about it. It has become easier to cope with over the past couple of weeks but I still wish I had never taken it. It was stupid and I shouldn't have opened my mind so early. Doctors think the male brain fully develops by age 24-26 and I shouldn't have fucked with that. I hope parts of my brain are not forever changed and that I can still do what I plan to do in my life.
Please let me know how things turn out Sam, would love to hear from you.
