I had something like that happen, to me too.
One day, I bought some yarn that I thought was a really pretty maroon color. Within about two or three days, I couldn't stand to look at it, let alone touch it. Like EssenceRose said, it got so bad I had to have my daughter hide it away for me because it bothered me so much. It only lasted about two weeks, but man -- that was weird.
Wish I had some words of wisdom for you... hope it gets better soon for you!
