Hi there, I need some advice about what to do when my brother in law comes to stay..
He has very severe psoriasis to the point where he can stand up and skin falls anywhere he has been
I have a diagnosis of OCD, and I know it is awful but I dread when he is staying over.
I feel sorry for him as he is the only single brother in the family, (which his mum, my mother in law, says is mainly due to his skin condition, how he doesn’t bathe regularly and keeps a very unkempt home)
My partner and I are at odds because I get so anxious and stressed about the dead skin that is everywhere, which I know is because of my OCD. But I genuinely cannot help it, I get along with his brother well and understand it is not something he has much control over.
I have been with my mother in law to his home and cleaned his home for him too to bottom to help him out because he never tidied or cleans.
(He has red carpet throughout his home which has a sea of cream dead skin over it because he doesn’t hoover up) his mum gets really angry with him and explains no woman will ever want to come back to his house because it is disgusting.
I have even suggested I stay at my own mothers just for the night as I cannot cope with stress of cleaning up dead skin off my dog, when he pets him, the toilet skin, and just anywhere he walks because it just drops off him at all times.
He recently stayed over and had to borrow boxers and a toothbrush because he didn’t bring his own! 
Has anybody had this problem and if so how do you cope with it?
I know I must sound like such an overbearing weirdo, but with my OCD I can’t cope with it, it actually made me physically gag this morning and I don’t want to do that in front of him when I’m cleaning up the skin.
Many thanks in advance for any advice
