Thanks for sharing your pain!
You need to put it all away for awhile...but DO NOT sell anything yet!
Take time to reflect and do other things. Understand why you wanted to quilt in the first place.
Take a vacation...sounds like you really need one! Unwind and enjoy!
If after a year, you don't get the "itch" to quilt again, then consider selling out.
But please, don't do anything rash right now!!!
Let us know how things are going for you...we all have our struggles! We are here for you!
