This post was actually really tough for me to read, because it read exactly like the suicide note a friend had sent me (and others) after his partner had died suddenly. It chronicled the joy and happiness in their relationship, her illness, his slow descent into desperation, and, after she passed, his resolve to follow her.
If the author of the post is reading these comments, your heart is in the right place, but just be careful and take care of yourself. Don't lose the forest for the trees.
