Obsession

Hi 

 Does anyone else experience with obsession over non objects.  I seem to be obsessed with a parking space and parking round my house. I have a particular spot outside my house on the end of a row where 98% I park my vehicle. If someone parks there or there's a sudden rise in cars which would threaten this space I get really stressed and anxious. I've tried explaining to neighbours and some understand. But I'm like obsessed. If I see a new car in the road I stress. It's starting to run my life which is not good and I need ideas on how to let it go but it feels impossible.  We have a space on our drive for our car but I drive a company van also but I don't like the idea of a van infrony of the house on drive. It would block the view out the window I would just see back end of my van.  Any suggestions would help.
