You sound distressed enough that you might want to go straight to a psychiatrist. Family docs can usually get to you more quickly, but sometimes they don't have enough time to fully assess your situation. They can help, however, if there is a really long wait to get in to see a psychiatrist.
I don't know what your situation is with health insurance, but often you can go to a psychiatrist without a referral if you just call your insurance company ahead of time.
Good luck...hopefully it's not bipolar...
