Hello Everyone,
I am new here today, and I need some help. I am concerned about my brother. He is 29 years old, and his behavior is growing more strange and is really beginning to concern our family. He has very few friends, and doesn't strive to keep his friendships. He has never had a serious girlfiend in his entire life. I know he's had a few flings, but never a long term relationship. He never seems to want to get out of the house and experience anything. He's very socially reclusive, and he is spending a great deal of time playing violent video games such as Grand Theft Auto. My brother also has violent mood swings. One moment, he can be very passive, calm, and even crack a joke, but the next moment, if something is said that he doesn't like, or if something annoys him, he wil literally fly off the handle and begin yelling and throwing things. For instance, my fiance and I drove 300 miles to visit my family this past weekend, and my brother is staying with my parents until his house is finished being built. My brother stayed in the game room all weekend playing his video game, and didn't make an effort to visit with us or have dinner with the family. When my mother coaxed him to come to dinner, he was rude to my mother, and sat through dinner quietly, despite our efforts to speak with him. Then he began playing his video game, and played the rest of the evening, and then continued the next day. He became annoyed because the family was being a bit loud, and I was talking a bit of baby talk to my dog, which apparently annoys my brother, and he suddenly spouted out in a fit of rage, began cussing, and threw the game controller at the tv, and stormed upstairs to his room, and grabbed his keys to his truck and left. He didn't bother to come back to say goodbye, and we don't get to see the family that often. This isn't the first time I've seen his sudden display of anger. He's seems very fascinated with violence, and laughs at violent scenes in movies. He also asked my mother if they had bullets in their gun the other day. (They immediately locked the gun in their safe). My mom, dad, and I are extremely concerned that he's going to hurt himself or one of us someday. My dad is going to try to speak with him today to see if he will get phsyciatric help. My dad is even offering to go with him and do it together.

Has anyone ever seen or experienced behavior of this sort? I am convinced that my brother has some sort of disorder or chemical imbalance, maybe coupled with some issues of insecurity and perhaps some issues that we don't know about because he never communicates anything to us. Can anyone tell me if my brother's behavior may be linked to a mental disorder or illness? Can anyone offer any advice on how to deal with my brother if he refuses to go get help?
