I Am Misunderstood

My whole family misunderstands me. It has not been easy to say the least. They take out all their stress on me. I ask for a little bit of help with something and paying them back and they scream and get in my face. But they always give my brother the world like they never wanted me. And the worse thing is that they act like their angels around both sides of the family and they think i'm the reason my family can't get along. It sucks being looked at like the monster. I don't know what to do until I can move out next year to make life better other than going to visit my boyfriend for a week every few months and get a round trip plane ticket to do so:/
