Hello there I am wondering if anyone knows a "cure" for OCD or at least how to calm it down. My sister has the disorder and it is a complete nightmare living with her its like living with cinderella this is probably why she is losing so much weight. I don't really know that much about it but she got diagnosed not too long ago, she is really bad she can hardly go out the house as when she does she wants to be back to tidy up.
