I don't think I'm going to help my family out anymore.
Why would you not help  your family?
They are not nice to me.
Family can be great, but sometimes they're not. If you feel like you aren't being treated well by your family then it may be time to set some boundaries and do your own thing.
Yeah, I think I need a break from them.
It's good that you're recognizing your limits and taking care of yourself. Good luck.
