That sense of control you have is an illusion.
All OCD helps you to control is your OCD through the relief you feel by performing compulsive behaviors over and over again. When that relief occurs, it feels as if you have averted an uncomfortable feeling or a dire consequence (such as keeping someone alive because you counted to 10).
This relief is only temporary, though, because the obsessions often return. If OCD really did allow you to control things, then you would need to perform the ritual only once and then never need to do it again because then you would have established control, and there would be no need to reestablish it.
Also, if OCD really did help people to control their world, then we would all want to have OCD.
Of course, this would bring about chaos because person A would want to control the world in his or her way, whereas person B would want to control it in an entirely different way. This would just not work. So, OCD does not actually help you to control anything. In fact, your OCD is probably in control of you more than you are in control of it.
If you want to have a true sense of control, do what you can to eliminate your OCD, and then see what life is like not being controlled by a mental disorder. This will probably feel much better than always following the rules of your OCD.
