In that case ask yourself if this friendship is really worth keeping. If she is excluding you and ignoring you and the whole thing is causing you more harm than good than it is probably better if you both part ways. Try to widen out and make more friends because real ones are very hard to find. Try to look for help for your financial situation too. There are special programs to help you with housing and food expenses, I know about a few in my area but unfortunately you live in another state. I'm sure you'll be able to find something similar in your area if you do a little research.
