Well my friend has been talking about me behind my back and i just cant take it any more its like I'm her puppy she can drop me when she wants and come back to me when she wants I am just sick of it!
Just ditch her, a person like that is bad news and not worth having as a friend. There are plenty of other people out there who will be better friends. There are always groups and activities that you can join and find people of like interests.
You do not have to let her make you feel bad about yourself and you do not have to work hard to make her appreciate you. That type of person is poisonous and in the end she will get left out when she does what she does to you, to other people You are worth more than that.
