1. Does this sound like OCD.?

I constantly double take ( doing the same movement over and over ) To stop myself from doing this it may seam wierd but i count to three and then that means a hate Someone that i liek if i do it again ( wierd ) If something isn't PERFECT i just can't do it. Like my bike, one of the brakes had a problem with a 250 game system i just bought, so i never play it because i don't think its perfect. I am always constantly thinking about a brain tumor. And also if i have to go to the bathroom just a little i have to go then or else i will constantly think about until i do. Then when i go to bed i have to check everythign in my room ( liek if the window is locked ) before i go to bed because i fear a "bad guy" is hiding in my room. ( stupid i know. ) And there are other things that i just can't explain. When i was little i used to wash my hands constanty and this is the first symptom i ever have remembered having. I sat there and i had to count every corner of somethign on the TV show that i was watching.

2.Im pretty sure my dad also has OCD. Does it run in familys?
