Please help me its an urgent mess!!!?

You deserve so much better than her she is only using you and she knows that when she calls or comes to see you that you will drop everything and give her the attention that she wants. You need to ignore her and not give in to her, you need to get on with your life go out with your friends and meet a nice girl thats not going to use you and treat you like rubbish. It will be hard but be strong and you can do it.
