My friend screams, curses, and at times, seems threatening towards us. He talks to people that don't exists. He claims to have albino snakes in his closet. All the neighbors within a 2 block radius can hear him cussing, screaming at the top of his lungs, and it's scary to hear all that. He has some medical issues also. Iv'e noticed is over-weight, has severe swelling of feet and legs to the point of using a bucket to urinate in. His mom feels at the ends of her rope and cries to me about him. She's 90. How can we get him help without getting hurt?
