Oh Lenore, what a tough place you and your husband are in! Sometimes this thing just never seems to end. There are people on this board who are bravely fighting through repeated treatments, and I know your husband can too if necessary. There are many people here who know what you are feeling, so never think you are alone. The "one day at a time" philosophy works very well here. Nobody knows what the future holds, so wasting a lot emotional energy on that depetes you.
I am blessed with an optimistic disposition, and have not experienced depression. That said, many people here have and I have read many recommendations for getting help via counseling and/or medication. I strongly urge you to investigate this. Ask the doctor, the nurse, the social worker at the hospital -- just start asking for help, because your fear and hurt come through so clearly. That you have come this far tells me you have a lot of strength, and I know you will be able to handle whatever is to come.
Let us know how you and your husband are doing, Lenore. We care.
Joanna
