I just saw your Post in the 'How are you feeling thread' i felt exactly like that a couple of years ago. Im probably not the best person to take advice from, I still feel like that a lot of the time. You still have plenty of time to get your life going again. Im the same, I don't know what the hell I want to do with myself.
Waiting around for something to happen is my biggest mistake. Ive wasted 4 years of my life. I suppose what im trying say is you still have every opportunity to make a life for yourself
Oh, and I'll wish you a happy 18th, for whenever it is.
