About 6 months ago I left my handbrake off and my car rolled into another car.
Ever since then I've become over-paranoid, when I park up I check several times I've put the handbrake on. When I lock the car I peer in and check again. As I walk away from the car I'm looking back, checking it's not moving. Sometimes after I've disappeared from view, I've been known to have to go back and check again.
I'm scared I'm developing obsessive-compulsive tendencies around it (have had OCD in the past).
How can I get over this??
