Hi, ALD,
I'm sorry you had to join our club, but welcome. Dementia is an awful death sentence, and for someone so young, it is even worse. It must have been terribly difficult to see the initial symptoms and be baffled at the behavioral aspects. In a way, I imagine that it was a relief to know why your wife had changed, but to then know that there wasn't hope of improvement must have been incredibly difficult.
Having worked in skilled nursing facilities, I've seen how people have had to make the decision to allow other people to care for their loved ones, but it is doubly hard when the person is young. I know what it takes to be a caregiver, as I also took care of my first husband for 18 years. I hope you truly know that you did what was best for your wife - and your son - and thirdly, for yourself.
It isn't at all unusual to be hitting a wall at 8 months out. Even though you knew the outcome for your wife's life for some time before her death, there is something that hits us when that day finally comes and they die. I have said that I was well prepared for my (first) husband to die, but not for him to be dead. You go home and shake your head and say, "Wow. This day is here." Then we go about taking care of arrangements and the tasks of everyday life such as taking care of your son. Eventually, for many of us, we get gobsmacked several months down the line. "Is this my life? How do I move forward from here? How am I going to figure out how to live my life again?"
Well, I'm rambling on...but I wanted to welcome you into the fold. There are several new people who have joined recently that are just as freshly widowed, if not more so, than you. I hope you all can find support here.
Maureen
