Keeping yourself happy?

I know exactly what you're talking about. At that age, I was pretty much in the same boat. I had cut off ties with my family, and I was living alone in a new and unfamiliar place. I also had the same coping methods... music and driving. Sometimes I would drive around all night because I loved how peaceful everything was at night without all the hustle of the daytime. I could listen to music, and just drive around seeing things without being bothered.

I am not sure what you can do to pull yourself out of the doldrums. What worked for me, ironically, was finding friends with whom I could relate. I have been lucky enough to find interesting people that I could spend time with, and learn from, which helped me mature and grow. I never needed a lot of friends and attention from other people, but having face time with people I found fun and interesting was very important for me to develop interests in things I would have never experienced otherwise.

The only answer I can conjure is to somehow connect with whatever it is you feel you're missing, and try to find a way to fill that void. Especially at that age, you probably would do well with a sexual partner, as well. Just don't get stuck in the aloneness and allow it deteriorate your mental health.
