I'm trying to get information on possible mental illness of a family member. This is a long story and I hope not to jump around and I'll try to make it as short as possible. Any help or ideas I would greatly appreciate.
My brother is 43 years old. He is an alcoholic and a drug user for many years. What I would like to know is if substance abuse for all those years can cause mental illness? His troubles started when he was 13 and his best friend killed himself. He has since shot himself in the hand and told us that someone shot him. Took a knife out of the house and sliced himself. Stole cars, money, drugs (anything not nailed down),stalked girlfriends (any and all of them), in and out of jail all his life. He has nothing and doesn't strive to want anything better for himself. My parents have had him evaluated when he was younger. They found nothing. They took him to a psychiatrist, they found nothing. They took him to a boys home but they said he was fine. He has a hole in his spine from birth which I think contributes to his issues. He has nerve damage. He has the shakes but I don't know if it is the hole in the spine or the drugs and drink. There have been many things he has done over the years but this last year was it for me. He called me to tell me his ex and his daughter were having problems with her husband and that he was trying to help. He told me that someone put cement down there water pipes, ransacked the house, threw paint on the walls and stole stuff like a laptop from the house. Cops later found the laptop behind the trailer my brother lived in. I told the cops I suspected that my brother did it all but they couldn't do a thing again! What I am getting to here is he did all these acts and made it look like the husband did it. And mostly everyone was believing it. He has elaborate stories to tell and none of them true. He just lies and he actually thinks it's believable. None of it is true. This past weekend he couldn't get in to my mom's house. I have another brother that lives with her and takes care of things around the house. So he has become a target for the brother that has issues. So then he decided since he couldn't get in the house he would break a window, pull the cable wires down and pile lawn furniture and trash cans against the door. Well I had him locked up on a domestic relations warrant but that will only give us a break for maybe a couple days. There is so much more he has done and so hard for me to explain. I think something is mentally wrong with him. My fear is he is going to kill either my mom or my brother or both. Like burning the house down while they are in it. I have told both of them my fears and it turns out they also fear the same. I also expressed this to the cops and they just blew it off. If it is a mental issue I don't know how I can force him to get help or keep my family safe. Anybody have any ideas? I would really love to hear them. I just want to keep my other family members safe.
