It makes me sad, but I'm starting to hate all the people in my life that I once loved.
I'm sorry to hear that. Why are you starting to hate the people you love so much?
They give me too much shit and I can't take it anymore.
If people in your life are getting you down, you should be honest and talk to them and discuss how their behavior is affecting you. If you keep your emotions bottled up the people who you formerly loved won't know that they should change and you'll end up hating them for their behavior. Instead, airing out what is bothering you will lead to a healthier and closer relationship with those you love.
I already tried that but they don't listen to me.
That must be really tough, but I think you should try talking to them again. I'm sure if really let them know how they're making you feel then they'll try to change their behavior.
