I'm pissed at my friends
Why are you mad at your friends?
Because they never  support me in bad times, they're always busy with their own lives.
I understand you are upset that your friends are not there for you when you need help and are sad. But they have things in their own lives that could be causing them strife at the same time.
I'm willing to lose them for their behaviour. A lot of things need to be changed so it's worth it.
You have all the rights to get mad at your friends. They're not your true friends if they can't be there when you're in need of support. I'd suggest you to part with them on amicably.
