I have OCD, and do a similar thing with the breathing. I'll hold my breath in elevators, and sometimes actually expel all the "bad" air from my lungs and don't breath until I get out. I have a habit of banging my glass down onto the table, or grind it into the table, before lifting it to drink. I often need to reach out and touch the thing that is just at the corner of my eyesight. Yes, you have some OCD behaviors. Do talk to your mom. It's important not to keep things like that bottled up inside.
