I couldn't do without the knife, I use it nearly every day for something. Opening a package, peeling an orange, etc. What's weird is when I'm not wearing jeans

I couldn't do without the knife, I use it nearly every day for something. Opening a package, peeling an orange, etc. What's weird is when I'm not wearing jeans or pants/shorts with pockets--say a bathing suit. I keep stuff in my hands, then--but I feel really paranoid and I keep checking and rechecking to make sure I still have my wallet/phone. When I break this habit, I end up doing things like locking my keys in my car.
