Mary, my dear:
I have carefully read your post - twice. For the life of me I can't identify a problem here. Don't be so hard on yourself. In the general scheme of things, you appear to be conducting your life in a manner befitting any well-adjusted quilter of the 21st century.
You obviously have a love of fabric, evidenced by the amount you've acquired and the way you've stored it on shelves, in bags, tubs, buckets, etc.
You are careful with your quilts, evidenced by the care you give them in covering them with sheets and rolling them rather than folding and creasing them.
You've had your DH build to shelves to store and display your fabrics, which speaks well of you.
If there is one thing needed to ease you into a state of true comfort - it would be to have DH build you more shelves. When He built the first ones, he obviously didn't take into consideration the growth you would develop.
All in all - there's nothing wrong with you that a few more shelves, and perhaps a room addition, can't make right.
