Hello Polly Anna,
my heart goes out to you right now. You are in one of those corners that you cannot move from because of your dedication and love for your husband.
as Tracie said there are many who understand your position and feel with all our hearts the pain, the desperation to have comfort and peace for your husband especially - and for you and your children.
just take one hour at a time, take breaks when you can - fresh air, a short walk, clear your head for a while, and know that the gift of love you are giving is priceless, priceless !
its true, animals seem to be treated better than humans when it comes to end of life.
as a caregiver (retired ) and as a family member who has lost loved ones, I hear your pain, I feel your emotion, your love. Your husband hears you, feels you, loves you but cannot say so
you are an amazing caregiver
keep writing, keep sharing, keep letting out your hurts and emotions, it does hell.
wrapping my arms around you from a distance
sincerely,
NatR
