How can I stop all this depression and fighting...?

Please no hate comments... This is serious. Like all this stuff is happening... I can't cry anymore because I cried alot this week. My moms like,"I wish I could just go..." and my dads always cussing. He has serious anger issues. My brother's kind of a ***** and he's on no ones side... and i'm stuck in the middle... my mom already took away my PS3, screamed like a metal patent, and when I said,"I prayed for forgiveness!" She said,"Oh please..." little atheist *****. And my dad screamed in my face 3 or 4 times. I get scared shitless and I feel like he could just stab me or strangle me when he does it. My brother started it. I think my parents could get a divorce... I try to say sorry, but no one forgives me even when I really mean it! They say,"The damage is done Kevin." or some stupid stuff like that! It's horrible... I don't remember a good time with them... All this fighting... my best bet is to put myself up for adoption...
