Yeah. It's not something you can just make a snap decision about. And, I wasn't too good at meeting new people, either. But so long as you don't go starting trouble and making too many enemies then I'm sure you'll be fine!
Ah, don't worry about it! I like the idea of helping people, and if my advice has helped you at all, then that's all great! ^^
Yeah. They tend to do that. Put pressure on you. But, really. When you do decide what you want to do- christ you don't even have to go to college, if you don't really want to. Just take your time. Weigh out pros and cons. Decide what you want to do carefully. Otherwise you might end up hating your chosen career, which in turn might make you hate yourself at worst or, at best, you'll get bored and mess everything up but be stuck with it for a long time to come. :/
