I think many things are overwhelming these days. Ever been to a garden center to look at plants? Or try to choose a healthy grain bread? Sometimes too much is just too much.
I've been where you are and a few times over the last twenty years I went thru ALL my craft and sewing supplies and donated them to either the local nursing home or Goodwill. Some were ambitious purchases and some were "OMG I HAVE to HAVE THIS!!", then a month or so later it was more like "what the heck am I going to use this for?". Over the last few weeks I have decided to sew for me. But what? So I would like a summer handbag and am looking for videos and books to do just that. You don't always have to sew for someone else to feel good, sometimes sewing something simple, even just a pretty, flowery coaster for your coffee mug, is so much more cheery that you would expect.
My suggestion is to sit outside on the warm days and watch nature and the trees and the butterflies and listed to the birds chatting with each other. Just sit. Take it all in. Then go inside, pick three of your favorite fabrics, and make yourself something just for you. That will tell you what direction you need to go in. Then you can figure out what to de-stash and what you would love to keep. As they say, less is more. Keep what you absolutely love and donate the rest. Your mind will clear up and you will feel freer. Happy days are ahead!
