I don't know if this is quite the same as what you experience, but I can have a very difficult time deciding on anything, even something as simple as picking clothes to wear for the day can take a frustratingly long amount of time for me.

Also it takes me quite a while to make selections like at the grocery store or when i have to shop for anything else, I might spend 30 minutes trying to figure out which one of an item to buy. If I write a list I still manage to forget things on it...I always misplace things, which just adds to confusion.
