About 20 days ago I was doing fine, I was a little more focused with school and started drawing again. Last night it all went to shit. I have an adopted brother that hates me for no damn reason. I've confronted him as to why he singles me out and ignores me or straight up treats me like shit. He pretends I don't exist even in front of my parents. I've already talked to them and literally begged them to do something about it, to at least say something.   
All I want is to feel is I matter to my parents and to let him know that it's not right what he does. All I want is for that asshole to stop. But last night he even got physical with me when I asked him why he hates me so.. he totally started shaking (it was scary and disturbing) he grabbed my hand and pushed me out of the way.. He acted so tough and said he doesn't need to talk to me he doesn't want to look at me he has nothing to say to me.   
My parents got right when I was crying and arguing and the asshole literally made an innocent face acting like I was the beast. That made me even more upset. I called him out on the bs and my parents didn't even listen to what I had to say. Right away my mom sided with him and started comforting him, because I'm such a monster attacking him... wtf.... my dad called me spoiled brat, always seeking attention and playing victim... (wtf). I've been so insistent on this because they don't listen to me. They are in denial, they don't believe me.   
More than being hurt, I'm so angry at my mother for immediately blaming me. She said I annoyed him and accosted him and that's why I got that from him. I'm like HEEELLOOOOOOO!! THIS shit is borderline domestic violence, what the fuck. (its not the first time it happens, and last time he was about to hit me, she was there and said nothing) Im not stupid, it's sooo obvious that asshole has a problem with me. The worse is I don't know what the fuck I ever did. It's been years and I'm sick of this shit. I can't live like this anymore. My mom instead of addressing the disturbing behavior on his part, basically started telling me that she was not gonna allow any disrespect from my part and make him feel bad...? wtffff... I called her out on that massive bullshit because she lets that happen to me, she lets him get away with anything. I feel like I'm going crazy. They tell me its my fault, (and start talking about my "attitude" aka my depression. how I don't go out, how I don't have friends, how I don't talk to people, they say I'm spoiled and I'm disrespectful)   
After all this... I just realize how lonely I am. I just want out. I need help. I can't go on like this.
