Washing impure bed sheets

Q: My question is on behalf of my colleague. He is having a problem since 6 years. His life is in danger as his parents are not with him. His parents are in India. He lives in his uncles house. He told me that one day he was sleeping without going to toilet and he urinated while was sleeping in his bed. He is very shy to wash his bed sheets because he will be asked by his uncle and aunt. After that he washes his hands regularly and they thought he got ocd because they don't know his matter. They took him to the doctor. Now he's afraid of tell them about his problem because if he wants to wash his bed sheets they say it's washed and his duvets are not clean as well. They always follow what he does. So brother please tell me what should he do now? He's always thinking about it. Please give him some advice.
