Should I tell my doctor about this?

I have to have something on the the floor. like a rug or towel or blanket and even growing up i always had clothes (could just be because of teenage years) but now its getting stronger. i cant sleep without it, and i have to have lots of pillows. all against the side of the wall plus some to use. Right now i have 9 pillows plus a smaller square one. I also have a tendency to worry about things if i did it right and what would happen if i went back and did it a different way, for instance turning the rug a certain way or not stepping on cracks. My mom has OCD and i was wondering if i should let my doctor know about these things. My friends laugh at them so im guessing its not normal?
