I have a thing where I'll be doing something and I get an urge to touch a certain spot somewhere and if I don't, I don't feel satisfied. This feeling comes when I'm doing practically anything. I'll be going up the stairs and I get a feeling of "you have to touch the corner of the wall where the railing ends or you will feel weird". I can stop these feelings by imagining me doing them but then more will form. I wonder if there is a word for this or if its part of a mental thing.
It would be like: "I have ____. I can't help it" or- "I feel ___". I don't know what form of the word it would be.
