Under stress

I really can't believe the amount of stress I am under. My partner used to be so strong physically and since he has been diagnosed with COPD his whole lifestyle and attitude have changed. He can't breathe, he is depressed, and he doesn't believe he will be alive much longer. He turns 60 in May and watching him fall apart is really stressful. On top of this I have the horrible confirmation of yet another spine surgery. I expected the one at the bottom, but had no idea as to the complicated involvement of the upper disc. Having to wear a halo scares me to death. As usual my girls don't understand and they minimize the idea of wearing a halo saying it won't be forever and that I should look at the long term not the short term. not real easy to do. As usual no one to talk to. No one understands. I am 49 days smoke free and I am trying really hard to stay away from cigarettes. The good thing is that he no longer smokes and I am medicating myself so much I wouldn't try to drive. 
(The scary thing is that my second husband turned 60 in May and passed away in August). I have that hanging over my head as well. Not much to smile about here.
