What a terrible thing to happen!
I think sometimes it's hard to do anything that will give you pleasure, when there's so much bad stuff happening. It's almost like we feel guilty for enjoying something, especially while your daughter is still suffering.
Quilting can be therapeutic though, like art... perhaps something for your daughter, to help her recovery, or something more abstract you can put your own feelings into, whether it's dark and angry, or whatever. Maybe a wall hanging to auction for charity, or to help your daughter. Or even if you make something that you'll put away and never look at again. You can put so much love into a quilt for someone, you can also get rid of a lot of bad feelings the same way, by putting them into fabric.
And Welcome to the board, there are some very inspirational men and women here, and there's always someone who knows exactly the right words to say. You won't meet a lovelier bunch of people anywhere.
