I understand. I've been there. What's worst is them not stopping by to visit you when they are in the neighborhood. Or when you go and visit them at their house and they're busy doing housework or spending time with an aquaintance. You sit there alone thinking "Why did I waste my time? They act like they've got better things to be doing."

My family is like a bunch of actors on a stage-everyone is trying to out drama the next. Me, I'm not into the whole drama thing-which has left me sitting in a theater seat by myself and everyone is too busy performing to come by and sit to talk with me.
I deserve better. You deserve better. You'll have to learn not to need them in your life if they cannot treat you like you are somebody who's loveable and special.
It's easier said then done but if you don't then it's going to chip away at your self esteem and self worth-which can be devastating.
By the way, the one response you got was a little unsupportive and preachy. You have the right to your own feelings. You're in pain right now and you're lashing out. You're allowed to be angry. It's all going to be okay. Hang in there.
