<human>: I'm 16, and male. It sounds stupid that I'm worrying about something that may or may not be really small, but I just can't fucking take it any more. When people I'm close with (particularly girlfriends) tell me they used to drink or do drink or smokes, I just can't overlook it for some reason. It just picks at my insecurities so, so much and I can't really work out why. I know it might not seem like such a big thing to worry about, but in the next few years I know all of these drugs will play a huge part in my life, for better or for worse and I don't think I'll be able to cope. I need to find a better way of dealing with it, but I just can't. I don't know what to do. I'm not a shy person, or someone who worries about being social. I do have friends, don't get me wrong, but I worry that if I get close to anyone someone like this will happen and it will destroy me. I can't tell anyone, either, it just doesn't work like that. I don't know what to do, and it all scares me.

Can you give me a shortened version of the text?
<bot>: people getting older in high school and then doing weed, drinking alcohol a lot or smoking bothers me, even if they don't do it any more and I worry that it will ruin any future relationships I want to start.
