Depression.. help, fast!?

Okay well yesterday I went to a party with my friend and we were supposed to sleep out and it was all okay until she went swimming with her clothes on and i didn't want to, so then I was left alone- not knowing anyone else in the whole house, trying SO HARD not to cry.

Anyways, I decided to leave and I didn't end up saying that to my friend because I was so angry and upset, now she's mad at me but I just don't know what to say when they ask 'why did you leave' or 'why didnt u tell me u were leaving?'

What do I do?
PS my mom doesn't take this seriously so I haven't seen a doctor..

I keep telling myself this won't happen again but it does..

I get so angry I'll say things I'll regret.. so I'm trying not to talk as much when I get in those moods.

Or sometimes I just want to kill myself.

These mood swings keep going back and forth, which makes it worse..

i know how you feel. your friend shouldn't get mad , but you cant control her. you did what you felt was rite and you mite have been. if your friend gets mad and treats you like that maybe she's not a good person to be hangin with. about the suiside thing: DON"T THINK LIKE THAT!! you have a lot of people who care for you even though they dont show you. just remember if you don't feel like any one can hear you , you are wrong..... God hears you and loves you and doesn't want u 2 hurt yourself. i was depressed for over a year i didnt want to listen to anyone, and it led me more into depression. i used to cut myself overdose, and i thought i maybe could be love by guys,but i wasn't. finally i got tired of everything and i started trusting God. i started to see everyone who was my friends weren't, the guys didn't LOVE me they just wanted stuff, overdosing made me sick. i went to counsolors and they helped me a little, then i finally saw God was the only TRUE thing in my life. and got more close to church and everything feels so much easier now. my best friend(really good christian guy) after 9 months asked me out i said yes b/c i liked him since we met. i'm reaaly popular at the church now. everywhere i go someone comes up to me and gives me a hug.me & my boyfriend are doing great, my parents and me are getting along and me and my relationship with God is tthe best!! and you see if i kept partying and drinking and all the other stuff i kept doing then killed myself i would'nt be here rite now talking to you and enjoying life.god has plans for everyone even if you don't see it He does. god loves you so much he sent Jesus(his only son) to die on the cross for everyone. god doesn't make people to say they're a mistake in his eyes we're here for a reason. i'm here to be a missionary and bring people that have gone through what i have gone through to bring them to heaven and not hell. God has plans for you so don't give up. stay close to god and he'll bring you out of everything. b/c you can make it with him. it says it in the BIBLE: you can do all things through christ.
so remember my words and contact me if you need to. god bless you!

keep telling your mom, and if that doesn't help,tell someone else. there are many help lines you can call. tell a counselor, teacher, or other relative. or write your mom a letter, telling her you're actually worried and would like to see someone. tell her that you want her to take you seriously or you WILL find someone that can, and maybe she'll realize you are truly troubled.

um you might want to ask this question later, Y!A is messed up right now and your question is only displayed on the front home page.

if you don't get a lot of answers, don't think no one cares, its just that no one can help right now.

but to answer your question, you just have to tell her the truth. she wasnt very considerate to you. leaving you alone in a house where you don't know anyone.
