Honestly? Everyone would love it man,everyone would probably choose to deal with high school stuff. Chicks,looking good,etc. Thing is that wouldn't do you any good in the long run. I see high school as an experience. You go through all of these said teen problems,and you get out of it. The stuff that you did go through,some of it might benefit you and you learn from it. it's a step by step process into your "adult life" mate,
And you said you moved to a new city. That's great,take that as a chance to start fresh. Just tell yourself that the old you(basically staying at home and being lazy) phase is over. Make that change and tell yourself that you'll at least try and take the effort to communicate with people, or by taking care of yourself,etc. Hell,hit the gym. Set a goal. Follow it. You'll be surprised how far willpower could bring you. You cannot change what you refuse to confront mate.
And you're only 18,take it slow man. You can still be immature and mature while dealing with stuff that you've got to face. It's all about balancing it out & enjoying yourself at the same time. And did you move for college? if so,it would be much easier to deal with all these,lol.
