How do I survive my last year before I go to University?
Pick up a couple cool hobbies. Learn an instrument, learn a language, learn to dance, get in shape. Pick up a sport or a martial art. Do whatever. It doesn't matter.
I really hope this comes across as comforting and not patronizing: you're still just a baby. Honestly, my real life didn't even really start until university and I'm fucking fine. Never had sex, never had a girlfriend, didn't have many friends at all ... just keep your grades up so you can get into a decent-sized school with the kind of atmosphere you'll do well in.
A year is no time at all. It feels like a lot at your age, but it really isn't. Just use the time to pick up a few cool skills, keep your eyes open for anybody who might be worth befriending in the meantime, before you know it this'll all be a mildly unpleasant memory.
Yeah, start a college advice thread on here. Or google for one.
I'm not trying to be snarky, there's just way more useful advice than I could possibly write in one short post on here. Keep your grades up there too, sign up for as many clubs and student organizations and shit as you possibly can on the first week, any and all that you could see yourself being the slightest bit interested in. Once you've settled in a little you can start to narrow down which ones you actually want to participate in.
Pick a university big enough that if you fuck up somehow with one group of friends you can just find another. Don't get super fucking hung up on some idealized notion of what it's gonna be like, either; there's going to be a transitional period before you really find your groove. If you're not getting laid and getting invited to parties within the first month or even the first semester, that's really OK. You're gonna spend a while there, you'll figure it out eventually.
There's my sage advice. For more you're gonna have to start a thread.
