I think it's great that you called your husband at work to tell him he was an angel. Sometimes, we just have to remember to, make every effort to, show gratitude through our words, or the small things we may be able to do, to those who stand by our side without fail...sort of, as you put it, "an angel."
Going through what we already have to go through is tough enough, but, I know, personally, for me, my gf is my "safe place" and that she is more medicating, in her mere presence than any inject or pill has ever been. My heart goes out to anyone who has to go it alone.
