I'm certainly not knocking anyone, and we're all different, but I've seen the comment a lot lately around here that someone can't bear to cut up some bit(s) of fabric they have because they're "too cute" or "too pretty" to cut. And I don't really understand that point of view. All the fabric I buy, I like. Some of it I really love. But it's just part of my pallette to create the end product. I bought it with the thought of cutting it up to make quilts, so the idea of not doing that doesn't really make sense to me. I've never used a fabric then thought, Wow, I wish I'd kept that one because it was too pretty to cut up. Instead, I think, wow, that was a pretty fabric before, but now with these other fabrics, it's more than I ever could have imagined it could be.
If I ever did get to that point, I wouldn't think it was the fabrics stopping me from quilting, I would think that my focus has shifted, and maybe quilting isn't what I want to do anymore. So as others have suggested, maybe a break to allow yourself to refocus where you really want to spend your time and talent is in order. :-)
