I'm pretty sure my brother has hated me from the day i was brought home from the hospital. He would always hit me, make fun of me in front of his friends, call me fat, make me cry (twice on my birthday) despite me always making an effort to be nice to him. We don't have a typical 'sibling rivalry' thing because when I do so much as tease him he gets extremely angry and aggressive. I avoid being in the same room as him because I know he's going to ruin my mood. Anyone had a similar experience or have an idea as to why my brother would dislike me this much?
