Friends suck.

So I saw this post about someone's friend being a dick, and I related to it in a way. Anyway here's my problem.

So basically I have been friends with this girl since grade 4. And we are just heading into high school together. Anyway she's been ignoring me, I wrote this long ask message asking her why and that's she's been ignoring me so don't say that she hasn't. She said she hasn't been talking to me because she wants to maintain "healthy relationships" with the other friends that aren't going to school with us. I was with another friend, that SHE was talking to at the very moment!

I told her if she wanted to maintain healthy relationships then she shouldn't be ignoring people.

Anyway, a few weeks later my other friend posted on a public chat with the people that we went to primary school with said that she's still depressed and suicidal. (A day before that I had a long ass conversation with this friend about all this. I basically told her to talk to someone, she said no. I kept insisting that she should talk to someone, call a hotline again no.)

Again she said she was depressed and suicidal. I panicked and told her again to tell someone. I got a bit mad because she wouldn't. Then she said 'Chill it's a song!' I lost my shit saying 'you can't just tell your friend that you are depressed and suicidal and then say it's just a fucking song!'

I got kicked from the group by the friend who was ignoring me. I told them to add me back and they did. Then the girl that was ignoring me told me 'why can't you get this through your thick skull!! You're making this worse!' On private message. By then I had lost my fucking marbles. I was in tears and absolutely furious. I got my mum, and she talked to her.

After all this shit she apologised i said it's alright. When it's not. But I'm one of those people who want to leave a friend but can't because they don't want to be lonely. A few weeks passed and she still hasn't spoken to me. Until last night. I messaged her.

Any fucking way. I'm sick of her fucking bullshit. I'm not sure if I want to be her friend anymore. To be honest I don't. I don't know what to say to her though. Do I tell her?

If you have any advice please tell me. Thanks.
