I feel like most of the "big changes" that I'm making in my life were kind of thrust upon me- but none the less, how can I adapt to these?

I have a teaching job coming up in the fall, away from home. I need to take it, because I know it's the best thing I can do for myself and my future. There will be a lot of adjustments to take place- living with a lot of people, in a social environment.

I'm going to need to drop all my emotional baggage before I start this. There was a girl involved too, someone I loved more than anything, and one of the only people I truly connected with (at least on my end). But she broke my heart, and I'm going to have to really move on from not just her, but my shadowy lifestyle.

This will be a tough change. I feel like the dark, brooding, loner, artist parts of me are all going to need to disappear, if I am going to thrive in this world (well, all except artist). And yet, I will miss being a loner, I will miss being an existentialist, I feel like I ultimately want to return to my isolationist roots, but don't know how to make it last without starving. :/
