Find a way to get back to being oriented toward people, not stuff. Can you volunteer to teach quilting for a group like 4H, girl scouts,or some shelter or the adult ed program in your area. You could use your plentiful resources that way and feel good about it.
And for the UFO's have a party of friends or a church women's group come over and bind quilts, with a door prize drawing for one of the finished projects. The finished projects donate to good causes for their raffles or sales. (Suggest prices for the items, it helps them to realize the worth.)
You are right to deal with this at this time--it is amazing how quickly a blessing can become a burden.
Once you clear out the surplus, you will find joy in the craft again, perhaps after taking a break to persue some other activity.
