The longer you drag it out the worse it'll end up for both of you. That feeling that you need her and the situation as a whole (especially with her seemingly feeling the same way or at least very similarly) is called toxic love and won't ever do you any favours

Give this page a read, it's good for explaining what you're experiencing and how to try to get yourself out of the entanglement, which you ought to do asap because feeling low is just one of many ailments you can be afflicted with due to this sort of relationship

Either break contact completely or just go along with it but expect the worst (if you can).

I feel so depressed. Emotionally back and forth. I'm not even over her yet. I feel as if I need her in my life and that no other girlfriend that I'd ever get could replace her. Ha, call me crazy. I know everyone feels this though. Advice?

That's your problem.

Get over her before she wastes a lot of your time

Sounds like she is playing you emotinally buddy because she knows you take her back each time.
