Dealing with my partner with ocd psychosis following

I’ve been in this dilemma for 15 months. He went through rehab for alcohol and is sober now. Smokes cigarettes and weed but every day will shower for hours . Convinced he has a rare condition with his hair and tries to wind it out of his head daily . He also takes bits of the scabs and collects them to take somewhere to show people what’s coming out of his head. It’s infected, big bald spots extends to eyebrows beard and moustache. Convinced it affects his back also . Has seen medical professionals none understand his problem. He’s agitated, lost weight and will tell all about his problem . He looks like a homeless person. Many illogical statements and anger at myself for suggoany different course of action. Will sit on the floor of the shower creating new infection daily . I left once but he doesn’t care for himself ( clean food bills), foolishly I came back three months ago and it’s horror . Eggshells. I’ve found somewhere to move to close by as I’m afraid he will die if he is abandoned . His family are in Melbourne and want him committed but not prepared to do anything . He sees a psychologist but uses this time to amp up how terrible his condition is. I have many supports and am resourceful and just want to see him survive. After this length of time I know he probably won’t ever develop insight to get over this . .the relationship is dead but I’m struggling to leave a human like this, I did this once but am stuck trying to make sure he stays in his job and has food etc. I’m sure there’s others out there trying to make sense or how to navigate, each day is scary where I am accused of all sorts of things. Many statements that don’t happen. I feel as though I’m strong but I’m losing my mind . @ocdpsychosis
