i have the exact same problem! was at the store the other day and dropped by wallet. bent down to pick it up kind of quickly and immediately thought "what if i hit my head against something on the way down or up?" it takes me an hour or two to calm myself down. if anyone has any thoughts on how to change this it would be great.

one thing i just started doing is "stop rushing and move slow". but you can't always do that unfortunately, and i forget sometimes.
