What is wrong with me?

I have a fear of the number 11. Every time I see it on the clock, I "know" something bad is going to happen to me. When I hear a cashier tell me my total and it has the number 11, i think about adding something else to my cart to make the number change, but then i cant bc its already too late bc i heard her say it. Its not always me though, for example, if someone tells me they have an appt on the 11th i think to myself that something bad is going to happen to them. If i look at the clock and its 10:11 and my husband is at work, i have to pray and pray for nothing to happen to him. The earliest I can remember worry about it was 9 years ago, and after 9/11 happened, it just added to it. Is it possible that this is ocd even though i dont do any wierd rituals to "make it better"? Also, I have gone to church my entire life and lately when people ask me to pray about their new job, or pray for their sick mother, i dont pray bc im afraid if i "waste" the prayer on them, God wont answer a serious prayer that i may need later. I know thats rediculous though too. When I watch that show Hoarders I start panicking and think I need to throw everything in my house away. The most important one that has me thinking about all of this is the other day, I was watching Dateline-To Catch a Predator, and while i was watching it, I kept worrying about if I would ever molest my child or if my husband would, and i got myself so worked up into a panic about if i would ever do it?! I know I would never do it but its like i worry about these problems as if they actually will happen if i dont designate a specefic time to worry about them. Whats my problem?
