family drama or not, you can only live 1 life at as time and your life is that life. No matter what else is going on, sit in your sewing rm, its your island of peace, and tell yourself, this is where my life is - whatever goes on outside of it is for other people to live.
I must say, no matter what went on w/ my husband and myself neither of our moms took sides, or even had anything to say about what was going on w/ us. They had their own issues in their lives. It kept holidays sane, it was like their homes were neutral to our drama, which wasnt allowed there.
What you do making quilts for hospitals is a good, happy, productive thing, do not let anyone get you down to the point you give up something so good in your life. Follow the true heart in you, look at your fabrics, touch them, sort thru them, design something - you will come away refreshed for it.
