My family invited me to come visit, but I'm not going to.
What happened? Why wouldn't you visit your own family?
I'm pissed off at them.
I understand how you feel, but you should still visit your family even if you're upset with them. I think you should visit your family and just try to have a nice time.
Fuck that, I'm not going to see them.
If you're really that upset with your family, talk to them before visiting. Call them on the phone and explain why you're upset so you can try to get through this issue. Then, you will feel better and will feel like going to see them.
