I do understand about not being able to sew right now. Give yourself some time. I witnessed an auto accident years ago where a 14yo boy was killed. I had a book in the car (I read every chance I get!) and I couldn't even pick it up to finish reading it for weeks....every time I tried that picture flashed in my head....the "impact" certainly impacted me! I don't think it could have been any worse if I had been involved.
So take some time, and as other have said, fill yourself with things that bring peace. It will come and the sewing will wait for you.
Sympathy to you in your time of loss.
