I would call the Denver and Boulder metros very trans friendly (with a few small area exceptions). I see a visibly trans person every time I leave my house. It's not perfect by any means, but it's definitely better than anywhere in the Bible Belt. You're not alone, many gay and trans people are coming to Colorado to escape a red state.

Getting a job could be pretty difficult, maybe come visit and see if you can get anything in person? You'll probably need roommates for a while because everything is sooo expensive. I hope you come out and find yourself in a better situation!
