This is going to sound really selfish. My dad has Alzheimer's, middle stages. I am grateful to still have my dad here, many of my friends have lost their dads and would give everything to have another day with them. Now here is the selfish bit, I feel like he is still here but not the same and I can't grieve because he hasn't gone but I get waves of grief. Then I feel guilty because its like i'm wishing him gone. Any thoughts.
