Is there a such thing as a bathroom phobia?

If not, does anyone know what problem I may have? Ok well I have this weird hatred towards bathrooms. I have certain things I do when it comes to them. I can't. Remember when it started, but for years I have had strange doings. I ALWAYS have to have to bathroom door closed. That is non-negotionable. I won't talk if the door is open. I don't talk in bathrooms, nor open my mouth / breath through my mouth. I won't touch the knobs on the faucet nor the door. When I take a shower I HAVE to wear shoes. I will not step on the floor. Also I won't sit on the toilet. Only times I do, I have to put toilet paper on the seat, even at home. Ill keep it super clean and these rules still apply. I've done these things for probably 10+ years and ill be starting college this fall, I don't want this to stop me from being "normal" in college. My friends don't think of it too much they just know that I like the restroom door closed and when they ask why I have to make up a lie. I'm really serious, any help will be greatly appreciated. Thanks in advance. C:
