My dear quilting friend - There isn't anything I can say to make you feel better. Being through breast cancer (two types) 3 years ago, I can tell you, there are some wonderful medications out there that will help you get through all this. Having your dear husband there by your side and to lean on is a blessing. To this day I give my DH so much credit for being the best nurse in the world and being there for me. (He lost his former wife to cancer so hated the thought of his having to go through it all again.)
My prayers are with you. Please let us know how you are doing. I'll gladly respond to a PM anytime.
