Why do I hate my sister so much? anyone can relate?

I can't stand her bitchy behavior, we were never close and it keeps getting worse as we grow older, we all live together, i can't look at her, she pisses me off so much, i have bent up anger inside me from years of abuse.

i can't hear her voice and cringe when i hear her name, yes its that bad!

i literally have much more love to strangers on the street than her, would literally cheer up if she disappears.

this can be due to still living at home in my 20s and had been single for a really long time, all the frustration building up in me making me so bitter and rude to all my family especially my sister who's also in her 20s.
