Andrew Luc,
It has been many years since I left high school, but I can remember the way I felt in the years following. I would describe it as a bit like what (I imagine) it feels like to be fired out of the airlock of a spaceship into the void. Everything and everyone I’d known for the prior 12 years scattered and I spun for a while, not sure what to grab on to, missing everything familiar to me. All my old friends were off on their own adventures. Some of them I never saw again, others were too busy to keep in touch with regularity. The new friends I tried to make in college lacked the familiarity of those with whom I’d shared childhood experiences and similar backgrounds.
It turned out to be the first of many times my life was transformed by drastic change. The only advice I can give is to tell yourself, while it does suck at the moment, it won’t always feel this way. You will slowly begin to feel the next stage of your life coming together, and while it will never be the same as your old life, it will be great again. You will be happy again. You won’t even miss the old life quite so much. Keep breathing and smiling, and as Anoniem suggested above, become your own best friend. No matter who comes and goes from your life, you will always have you. Sometimes that has to be enough. Hugs. 🙂
