I am so sorry for your loss of your wife, @FrankC990173 .
I am glad you reached out - many here know the place where you are right now.
I know the disease and I know you, as her caregiver, worked very hard and lovingly caring for her, both physically and emotionally, feeling very helpless at times.
She is at peace now, mind and body, free of all the disease manisfestations.
I know you will miss her terribly - grief is hard.
Stay close to the people in your life that can help you walk this journey; ask for help - especially during those periods when it seems so unbearable.
With time, the good memories will override the time that was so difficult.
Remember her in those previous 25+ years that you had with each other when you laughed, played, maybe raised kids and lived life fully - together.
I will say a prayer for you wishing you peace & serenity on this journey of days.
It's Always Something . . . . Roseanna Roseannadanna
