My heart goes out to you. This disease itself is such a slap in the face...but to see a person who has been like your mother become a shell of a person overnight is like being slapped down and then continuously kicked in the gut. My parents both are GBMers and I will admit that from most of the information I have read that it is much, much harder on the elderly. My dad was 71 and my mom is 75.
Mom and I have talked at length after losing my dad last year and then receiving her diagnosis this past June. She has commented about how dad had no quality of life...he was like your mother...paralyzed and bed ridden 2 days after his last radiation treatment...but it was clear that as long as he wanted to fight, she was going to fight with him. I guess what I am saying is that we always have to keep hope alive until the last breath. We didn't even make the decision to call Hospice until the day my dad actually died. They just never wanted to give up trying to beat this monster.
My mom just finished her first round of the temodar last Friday and she ended up in the hospital on Monday. I don't know what we will be facing when the time comes for round two...but I do know that if she wants to fight...I will fight all the way with her!! I have to respect her decision.
I don't know if anyone will ever know if they have made the right choice in this journey. I do know that the most important thing I have learned is that we just have to love the person through every step of it and do what we think is right at the moment. Every minute has now taken on a new meaning to me. Every smile I see on her face and every word that rolls from her lips are being hidden in the corners of my heart so that I will always have this beautiful time together we spent together safely hidden to reflect on later in life.
I wish you the best in deciding what to do. Just remember to love her as if every minute is the last. Your heart will help you know what's the right thing to do.
God bless ~
