I have a younger sibling who now suffers from withdrawal affects. One is he hardly sleeps and that causes issues all in itself. He has anxiety attacks or panic attacks, one time we found him trying to strangle his self. As well as he talks to voices he hears or spontaneously laughs at what they tell him. I love my brother dearly and want to help him. It's so hard witnessing the struggle he now has to face and how it is affecting his life. I'd really appreciate anyone who can give advice on how to support and how to help him out.
