Hello I have been with my boyfriend for over 3 years he's 19. He sees things that are not there and has become paranoid. He sees hooded figures everywhere. He thinks something in his room is hurting him at night. If he ever has a scratch he becomes very paranoid about it. We've been to a Dr before for it. He didn't want to take medications and refuses to go back. He doesn't take drugs or drink alcohol often. He was in foster care as a child and had negative experiences. I don't know how to help him or what to do anymore.I'm scared things could get worse. What should I do?
