All good advice from the others. We all grieve in our own way and find ways to cope that allow us to make it through the bad times. The pain never goes away and the hole they leave in our lives never closes, but we find a way to deal with that plus move forward. I still tear up and can cry at the weirdest times..seemingly for no reason..
You'll get back to your sewing when the time is right for you. Don't worry about trying to rush or force it.
