Ready to kill my famy

Brittany
I live with my sister,her fiancé and 2 kids (along with my fiancé and my 3 kids, and 4 of his 5 on and off throughout the month) . I know hormones are out of wack, but dealing with the yelling all the time is really stressing me out and I'm ready to go off on them. My kids are never happy....I can't wait to live alone again.
