College Anxiety (anxiety)
So you have no money, an unsupportive mother and health problems, but you've gotten things together enough to get into college, to line up at least some funding, and you have a girlfriend..... This sounds to me like you're stronger than you may think you are, particularly if you also have an anxiety disorder (an assumption on my part because you didn't mention it).
You've got reasons to be scared and anxious, of course, but don't underestimate your ability to cope. And getting to know your father sounds like a positive experience for you. Good luck with all things.
