Do you think I stink??????

Ok I have a dillema. I'm 24 yrs old and for the first 21 yrs of my life I have never had a soul tell me I stink. All of a sudden I had a breakdown you can say when I turned 21 over a traumatic event(has nothing to do with bo) and I got obsessed with the way I smell. Now I strongly believe I stink even though my family and doctors say I don't. I was put in a mental hospital and no one there noticed any odor even though the day the cops came and picked me up I wasn't able to take a bath. The whole time I was there I was obsessed if I smelled. I would take 3 showers a day. I stayed with a roomate who had bronchitis so she coughed alot and I automatically thought it was because I stink. But then I thought well if I stink then why is she always trying to be around me and never brings up a smell or anything like that. I am now back home and I do this weird thing where I hide around the house and wait to see if anyone notices a smell. Trust me they dont know I am there I hide when they are gone and they never notice a smell. Then I call them all the time and ask them if I smell and they insist I dont and get angry with me because I ask like a million times a day. I haven't been around people for 3 yrs I put towels under my door because I dont want anyone to smell me. DO you think I stink????????

Oh just some reactions I have gotten: Coughing, sneezing, I can't think of anymore right now but please give me your opinion I am at my wits end.
