OH gosh, girl!
Hang in there!
I understand on all counts what you are going thru.
Just try not to think about daughter and son,,,,meaning, don't think about where they are. I know it's easier said then done, but worrying isn't going to help either one of you.
Don't worry about a little "quirk" in the quilt. They'll know it was made with love, even tho frustration was in there too. Most people don't even notice the mistakes that we see when making them.
BIG HUGS to you!!!
