that sucks to hear man. i can kinda relate cuz i have a 20 year old autistic brother as well. having friends pass away sucks, ive already had 2 die this past year. keep your head up man and remember its you who can change your life, not anyone else. if your parents arnt there for you then just keep on goin. make something of yourself.
anyways, right now i am waiting for pizza to arrive
