It's off topic, but when I was very young, I was afraid of a lot of things. It limited the quality of my life. When I got older, I overcame most of the fears except for the fear of driving. I avoided every and any situation where I had to drive a (any) vehicle for years, no matter how big the obstacles were that I had to overcome or how stupid the excuses were I had to make. One day, after hauling 40 pounds of shopping home through the pouring rain, I decided that this is it, I will overcome this stupid anxiety. My biggest wish at this time was to hop into a car without any second thoughts and just drive through this big city to do my stuff, like everybody else.
So I did. Got a car, lived through 2 months of pure horror until I got enough routine and practice to relax. And then, I never wasted another thought on being afraid of driving. It's really liberating.
I do still worry a bit about stuff that anybody else worries about (money, fear of losing a loved person or pet, etc..) but there is no more *real* fear that controls me.
So, OP, try to relax a bit. Your OCD can control you but it's just things. Lifeless things. Wear your watch and your phone and stop worrying about it. Worry just eats much too much of our lives.
