I don't know what to do

Things are just coming crashing down.
I'm 14 years old and in the middle of a very stressful first year of high school. I've been depressed for several weeks and I just got the guts to tell my best friend about it yesterday. One major source of my depression was the fact that my other friends have basically deserted me, but my best friend has stood by me. So, I decided that, if I needed to tell someone, it should be her. She was fairly accepting of it but we got to talking and I told her that something she'd done had kick started my depression. She didn't take to that well. She ignored me all the rest of yesterday and most of today. I texted her because she chose to sit with a groups that she claims she hates rather than me and she said (and I quote) "Becky (one of her really close friends but someone I've been fighting with recently) was over there and i wasn't going to have a little pity party by myself, so i put myself around other people, ok."
Am I the pity party? This is how you repay me for the countless hours I've spent with you when you were going through tough times? You desert me and act like it's okay? I can't even believe anything that's happening right now and I really need some advice on how to talk to her before I go to school tomorrow because I don't know if I can face a single day without any friends.
Please help!

well i been there is hard when your in high school and you dnt have friends but sometimes is good to go out of your group of friends and find new ones... but im guessing maybe what you told her wasnt the best way to tell her. Are you sure u ment what you said in the way that u said it? sometimes we feel a certain way and we blurr out what we are feelin and not quite what we really mean.. but maybe you did mean it but to her she took it the wron way. try and call her and see if she responds or try and talk to her when she is alone... high school girls are mean most of the time because they dnt want to look like they are being dissed but try talking when she is alone so she doesnt make a big scene you kno and be calm not in an angry way but only ifyou mean it.. dnt just go to her cuz you need a friend... i hope my advice helps..

For one thing, one person can't cause another person's depression. It probably made her feel bad when you said that. We are responsible for our own moods and we cannot blame another person for the way that we are feeling.

I would do as posted above and call her or try to talk to her and explain that you still want to be friends. Maybe you didn't mean what you said. Or maybe it did come out wrong. But to try not to blame your friend for your depression. I hope that the two of you make up and become friends again.
