some1 help ;-; (T.W. vent!!)

Hi, this seems a little silly. I'm reaching out to a (basically) dead, retro app to discuss this. 

I'm drowning. Nothing feels real right now and I don't see the point of life. I've felt bad before, but not like THIS. 

My best friend is drifting away from me slowly. I'm so incredibly proud of the person that she has become. She has tons of friends, an amazing family and a girlfriend. I've seen her grow, and she's seen me grow too. The last time I felt this bad, she saved me. But now it feels like she is slowly growing to resent me. And I have other friends, yes. But she saved me. I owe her my actual life. 

And it seems like no one actually cares. My friends seem to just ignore whenever I express something I find important. I know that they also have lives and have things to do, but it seems like they all just need to one-up me at everything. I feel sick. 

In 7 days, I have to confront my abusive dad in court so I don't have to see him anymore. My mother talks about him like she never loved him in the first place. That man did horrible things and I never want to see him again. But my mom isn't a good person either. They're both narcissists. I don't think I want to live long enough to see my dad in court. 

My mom says that I'm not 'mature enough' to decide for myself. I'm 13 years old and ready to run away and never return. I feel like no one else understands.

I don't know what to do anymore. Can someone please give me something that might help? And if you can't help, at least a way to end it painlessly?
