My twin brother stopped talkin to me FOR NO REASON?

i dont know why my own twin brother stopped talking to me. he totally changed and i dont even know him anymore. he said that he didnt want anything to do with me. but before we were really close. he was my friend too and we even played with eachother on the playground at reccess. but he stopped talking to me for about a year now. he fast walks and says "discusting" in a really cold hard fast voice whenever he sees me. its just.. hes really scary now too. he has totally changed. people say that he does drugs, but i know he doesnt. i hope . he stopped talking to me about in the middle of he 6th grade. and now 7th grade is over. and he is hard as a rock and i miss him so much and he will never ever come around. he hates me. so i dont talk to my twin brother or my older sister at ALL not even to tell hem to come eat or if i have a question or if i need to borrow something . and it makes me so ****** mad because my family is basicly torn apart. i havnt talked to my sistet that i share a ******* room with in 2 years and my own twin mutherfucking brother, i havnt talked to him for a year now. and trust me NEITHER ONE OF THOSE MOTHER ******* MISTAKEZ ARE GONNA COMEmAROUND.
