I lost my passion

I was a person who likes to help people, and who likes people. Now I am drained and I don't want to work anymore. I hate people, I don't want to see even one person. I would live in a cave if it was possible. I'm tired of getting bullied and living the things I didn't deserve. When you are nice to people, they'll take advantage of you. And being nice or helping someone doesn't have any benefits to you. I am working with people and I am in a level where I can't do my job cuz I hate people. I don't know how I can like people back but that's just not possible. Every time I try to like someone, they stab me again. I'm exhausted
