Answer:
When a family member loses a loved one, they experience grief, pain, sorrow, and any other depressing emotions.
Explanation:
Revival is the resurrection of a deceased being, which one lived. Revival can be possible through immediate medical care, or those who are experienced in things like CPR, difibulators, or other means of saving a being.
This will affect families in a more or less likely positive manner, because the grief, loss, and sorrow they were feeling will be uplifted by a sudden relief of one they lost, simply being brought back to life.
It is a positive emotion, in most cases, for someone to be 'brought back' from the dead.
