Ever since he learned to talk, my brother (who is 2.5 years younger than me) has loved to call me names and point out my weaknesses as often as he could. And he would often lie to my parents about having done so when I ratted him out to them (of course, I don't rat him out anymore). And he has physically abused me, too, taking full advantage of my physical weakness in order to do so. It eventually got to the point where I was afraid to be home alone with him, and would lock myself in my room whenever that was the case. And I remember many times when he would chase me around the house, acting as if he wanted to hurt me, and I would eventually hide in my room or hide behind one of my parents (I would use their bodies as a shield of sorts). Lately, I've been trying to figure out why I have such bad self-esteem. Do you think that this could be the reason? And would it count as abuse? Or is it just normal sibling rivalry? I am known for being over-dramatic so I don't doubt that that's the case here. I figured I'd ask anyways, though, just in case I'm not. Thanks in advance for your response!
