I hate my eldest brother to the point where even talking to him makes me furious.
Why do you hate him so much?
He's a son of a bitch because he's a dishonest and a fucking whore.
I think that you should cut your brother some slack.  Hating your siblings takes way too much effort.
You don't know anything, he's a big thorn in my side and I think he'll always be. I can't wait until he kicks the bucket.
While it is ok to have these feelings, just realize that the anger and frustration is hurting you more than it is hurting him. Do your best to let this go, even if it means talking to him or just trying to let it rest.
