I have gone a long time without help and ignoring my problem and it is all catching up !

As long as I can remember I have allways had a type of ocd disorder, when I was a little girl it was constant thoughts of numbers, counting and spelling out words in my mind whenever I would read something. Now I am 19 years old and my ocd has changed to a differnt type. I can never feel as though my house and yard car,clothes,shoes,dishes Exc. are clean enough. I feel like evrything around me is filthy and disgusting if not kept up with everyday. Constantly I scrub the counters,floors,walls,tubs,shelves,furniture, and non stop vacuming and moping and laundry and then think that if outside is a mess anywhere within so many feet of the house then the house can easily be messed up again by the tracking of dirt and mud and Exc. I wake up and instanly have the urge to start the process of cleaning and then cannot lay down until this is done at night and evrthing has to be perfect for me to sleep. If I try to go the day without cleaning I can not relax at all there is the constant thought in the back of my head that i have to clean and evrthing is messed up and disgusting. This is so bad now to the point in which i break down crying I dont want to clean like this all the time but feel as though I must. people think I enjoy this cleaning and that is why i never stop but I do not enjoy it is tires me. I would just like to be able to relax without haveing to break my back in order to do so at least once or even twice out of the week. this is so painful, and I feel silly talking about this with others and seem like they think I am crazy. I can not mention the way I feel to someone without breaking down and crying. I dont know what to do ?
