In all the years I have been quilting and before that sewing I've never had that problem, even when I was trying to build up my stash. I still have some fabrics that are now not so appealing but those I just threw into a string quilt or something like that. I know that now being retired I can't replace my fabrics so giving or selling isn't an option for me. I would hang on to what you have for a while and if you still feel the same way then donate or gift the fabric. Good luck with your decision.
