I am so sorry for your wife's illness, but quite grateful to find many "kindred spirits" here. My husband was diagnosed with LBD early in 2018 at the age of 63. He is now in stage 6 of the seven stages....and....I....am....so sad and tired and overwhelmed at the responsibilities that keep popping up. Scott, one of the best contributors, wrote an excellent piece called "The Calvary is not Coming" and this post has given me clarity, strength, and the desire to finish this lonely journey with all that I have to give. (I hope someone will share his post again here, because I don't have the time to look for it...and it would be encouraging to you.)Friends mean well, but unless you have been in this position, they have no idea that it consumes your entire existence and pushes you beyond what you thought your limits would be.
As I was reading your post, I kept thinking that if the disease was mine instead of my husband's, he would be taking care of me just like you are doing for your wife. I know your wife is grateful for all that you are doing and, even though she can't express this very well, she is probably so sorry that this is the journey you both have to live. May God Bless you beyond all measure and may you finish strong and be able to look back and know you did all that could be done.
