I'm so sorry your family isn't there for you, Tracy. I have found that those people I couldn't count on BEFORE my diagnosis still can't be counted on. Let those help who want to help; they're doing it out of altruism not obligation. And altruism trumps obligation every day.
Take good care of yourself and I wish you nothing but great success with the trial. My continued prayers are with you and yours.
Hugs,
Trish
