Good morning, my OCD is awful. At night when I going to bed, it takes an hour sometimes longer to lock up. Is this normal???

When I'm going to bed, I have to check the windows and doors are shut, its takes ages. If the cat wants to go out then I start all over again. I check to make sure the dogs are in, I know they are but my brain is saying something else. I check the taps are turned off, the candles are out, everything is unplugged etc. When I put my shopping away, all the labels have to been around the right way, no 2 favours of cat food are together etc . Any ideas how to cure my OCD, I've been to doc but he tells me that its not OCD and everyone does the same thing. Surely not, please help!!!!!!!
