Jen, I've been there and it wasn't easy. It might not seem likely now, but things will be ok. Actually, better than OK if you are careful and smart.

Agree w/tc1, find a roommate, rent a room, maybe see if you can find some long-term housesitting or petsitting gig. I shared a one-bedroom apt in a not-so-great part of Philly when I first moved away from home after college. When I started my "career," I shared a house with two other gals.... You gotta do what you gotta do!

Sending you lots of good karma. Keep pursuing your dream of doing what you love (music), even if your "day job" pays the bills for now.
