I am so sorry to hear about your husbands progression. It sounds a challenge you have on your hands with but I understand what you mean as far as being thankful for what you do have. I wish I had some great advice for you. It sounds like you are doing everything you can with love.
My father had GBM IV (six tumors) three large ones and several were inoperable...He left us in March..I often had feelings similar to what you are expressing agfter seeing continued weakness.. especially with the radiation and steriods.. From the time my father was diagnosed he could no longer walk.. paralized on the left side.. so he was hospital bound tho we go thim out nearly everyday in his wheelchair. I know it is hard to see the 'progression' of this terrible disease. I tried to focus on the ways we could connect. on the times he had some awareness of who we are and of being loved.. I know that even people who cannot communicate can still have deep feeling and connection.
I can tell you about my experience with my father.. It was a gradual transition .. He would talk less and less thru the days..He would eat less and less. It was obvious he was not fully aware of everything and would sometimes say confusing things and sometimes be right on top of a conversation. A lot of that depended on how well rested he was. Trying to fight the disease and he fought hard was a draining experience for him. (as it was for us) He gradually grew tired and slept alot. It was a very gentle transition. It was difficult in the last few weeks becasue he was having heavy breathing .. and the medicines they use to treat this (I think it is called Roxalin)can cause fatigue and relaxed breathing so they wanted us to sign an DNR which there were varying opinions on in our family. Having it clear what his wishes are is so important and having all of this documented is helpful. We did not have much time to discuss this and by the time we did it was so hard for him to talk about. He had breathing treatments to help dialate this lungs. I think my father had excellent quality of care.. whenever he was uncomfortable we directly addressed the issue immediately. I think it helped to alleviate some of the helplessness invloved in having to succumb to forces beyond our control.. I am so thankful for all the time we had together and for the opporuntiy to connect with my father in a way that would never had been possible in any other way.. I know it is a time in his life that was very challenging but also one in which he felt the most loved and cared for in his life. and knowing that means SO MUCH to me.
take good care of yourself. I hope you are able to get enough rest and that you are getting lots of support yourself..
