That really sucks that your friend killed himself. Having lived through it, maybe you know for sure LSD was the reason he did it. But perhaps he was covering up something else. If I killed myself today, not a whole lot of people would know why. They might attribute it to something they knew about, but very, very few people know about the thing that makes me want to kill myself. So what I'm saying is maybe you're right - I certainly have no idea why your friend killed himself, but maybe it could have been something that was devouring his mind that he kept covered up.
