Jan that is far from being selfish. Your sister is already gone, and all that's left is the physical, fast-deteriorating l shell.
She doesn't want to be here.
And you can't bear to see her suffering.
The thing is, when she does die, the memories of the frail person that she is, will be replaced with memories of the person who gave you all so much joy.
For the life of me I cannot understand why doctors keep people so obviously dying, alive.
This was such a sad read, but written by someone who cares deeply for her sister.
Blessings. 💜
