How can I fix my contamination OCD?
I feel like it's getting worse everyday. I have to carry a separate clean bedsheet wherever I go in the house if I want to sit or lay anywhere to avoid getting my clothes dirty. I re wash my hands everytime before eating if anything touches my hand even a tiny tiny bit. I don't even sit on my own bed unless the bedsheet's washed again if somebody else has sat on it. I don't let my outside clothes touch tiniest of space where I sit/lay with inside clothes on.
I have to ask my mom/anybody if thry have washed thrir hands everytime when handing over the food to me.
I've got into fight with my brother and parents because they sit on my "clean" space many times, atleast 15+ in the last 2 weeks.
I don't want to live like this, on top of that my mom dad taunt me everytime and that I'll never get anywhere in life if I keep acting like this but I just can't help it.
