Need to get my ex back, please help!?

I would just take a big, deep breath. I would definitely give it a week or two. Give her some space to take a breather and to analyze things. All these troubles can put a great deal of stress on someone and it takes a little time to calm down. There's really not a lot you can do if she completely wants you out of her life. As a girl, I've said that MANY times to my boyfriend. Somehow, we always figure out how to work with it. Although we could just be a lucky couple. Some relationships are never able to reach their full potential and therefore can never work. If you're still feeling like you need to talk to her, try to talk to her. If she rejects you, atleast you can say you tried and there will be nothing more you can do. Unless, she comes back to you, begging for mercy. I know it's hard to move on and get over a love, but you gotta do what you gotta do. I wish you the best of luck!
