It sounds like alot what I put my wife threw.
The Peg tube will help, I did not have it, lost 112lbs, the chemo and radiation, I found while going threw it at the time I was the most angry and hard to put up with, but after it was over and started to heal it started to get better.
My wife came home one day after shoping I was in one of my moods, she just threw everything at me, told me she was not going to take this shit anymore and walk out the door, had to deal with everything my self for few days, made me realize what jerk I was. As sick as we are I became very self centered and forgot what I was doing to others. Being put in my place did hurt me at all.
