Do you think it's bad to think my friend has OCD?
Why do you think he has ocd?
His life is in a mess, he cleans his room every week, when the weather is bad he wipes windows 3 times a day
If you think he has OCD then you should seek some help for him. Otherwise it could be bad for his whole life.
I just don't want to hang out with him. I'm feeling extremely bad about it.
I understand his condition may make you feel uneasy. But you need to be there for them and help them get the help that he needs. That way he can get on the path to fixing the disorder he may have.
