My friend totally backstabbed me!! Now I'm depressed. What should I do?!!?

You should go up to those girls who arent talking to you in person and tell them what happened and how you tried to defend her. and tell barb that you really dont like the way jim is treating her. tell her that there are many other guys out there that are way better than jim. tell her she dont deserve to be treated that way. if she still ignores you and keeps being with jim. then she aint a real friend. she will regret it one day and relize that you were right all along and that jim is not good for her and then she will try to contact you and apologize and all that good stuff. dont worry... everything is going to be ok. it might not be ok today next week or even next month. but i promise things will get better for you. :) you dont need to be depressed for something that you did standing up for your friend. you are a really good friend for standing up for her.... she just needs to relize it.
