Hi Gamma, welcome to the Forum.
Sounds like you feel he singles you out. But, doesn't he really speak down to your Mother as well? What about your sister, how old is she?
If you feel depressed, you do need to see your Doctor and battle that one first, because suicide is never an answer, is it, they win, you lose, so why go down that path?
Maybe, he holds guilt? Feels guilty over your problems even though he didn't cause them and can't get past it?
He for sure needs anger management and councelling. But, your right, he puts it all back on you.
Can you work? Have you spoken to your Mother about just how he is now making you feel and asked for her help? Do you have an Aunty/Grandma you can privately talk to?
Maybe you could move out and live with one of them for a while?
