You poor thing! You have had so much to deal with! What a relief for you that your son was OK. My son gave me the most awful fright some years ago and it look me weeks to get up and going again. Dont feel guilty about the sewing! Have a little trip to your local store, check out the fabrics, look at the books, go home and do something small. How about starting one of the Baltimore Quilt blocks? You need only cut out little bits of material at a time, maybe simply pin them on till you're feeling happier.
Let us all know how you are getting on!
