OCD?

Patient: I am always afraid that my house is going to collapse or break down. When i am out with friends at night i always have this paranoia in my head. I am always afraid it will break down due to heavy furnature, loud music, heavy walking, etc. I always have to do these weird hand motions to deal with the thought. Also, i often have thought of myself aswell as loved ones dieing in trajic ways. I would like to know if i have OCD?
