hello......i have suffered from ocd for many years and have been being treated for it very successfully with prozac,,,,yes..the things you describe are symptons..the checking and rechecking and the strange intrusive thoughts......i had to chuckle when i read about your need to keep checking the door.....all my doorknobs are loose and broken from years ago when i "had" to keep checking them.....the urges can make you think that you're going crazy! but it can be treated and you will feel much better....please see a psychiatrist if you are not already and let him/her know whats been going on.....and i'd like to know how you do if you don't mind sharing that with me...any other questions or concerns...i'd be glad to help you with..julia
