I know this situation is so scary. there were many days i felt overwhelmed.. So we worked on doing the small things like lowering the bed as low as it would go if he wasn't eating.. to make him more at ease about the falling. Staying on top of all the meds is alot of work sometimes too.
My father had anger.. alot of it at times.. I 've heard men often are care TAKERS not receivers. my father was completely dependent on others after his diagnosis... All through the journey we were walking the fine line. letting him be as independent as he could be while gentle guiding him out of situations too dangerous or just plain not a good idea..there were times he would shake with anger. Its hard because sometimes I think my dad felt like our care was overbearing. it is such a fine line. I think at times it was a good thing to express than let it ball up inside him.. we tried sometimes successfully to redirect anger at the situation than at us. You are right the good days keep us going but the bad days also give us alot too. I know my dad felt so loved that we were with him always esp through the tough days. and what I remember most through those difficult days is the love. maybe its like childbirth you don't forget there was pain but lasting seed is the love and connection. I also know it reveals we have much more strength than we realize.
Remember you're doing an amazing job and keep a little time and space to renew yourself too..
You are in my prayers and I hope you and your husband continue to do well. Keep your hopes up. There are many people who do great on temodar for a long time.. there are other treatments too if that changes. No one can tell you how your husband will respond to treatment.
Be well.
