How do I avoid family? Anything I can do to remove myself for some time?

I know what you mean, and it comes from being around them all the time. Being around anyone too much can make anyone feel frustrated. Trust me, I've been there. You haven't said how old you are, but if you're old enough, maybe you can get a job. You won't be home all the time around them, so after a while you'll start to feel less annoyed by them. If you can't get a job, maybe you could at least stay with a friend? Or go hang out with friends most of the day if you can. Just get out of the house and eventually you'll start to miss being home.
