There is nothing worse for a parent than losing a child.
Maybe my 18 y.o. DD 2 will let me give her a hug.
There is nothing I can say to make this better for you.
The trouble is,
It may hurt MORE because of the strong bond you formed with her.
The bond that made her short life so happy.
The love for her that helped her grow into the young lady you were justifiably so proud of.
Maybe you can get some small comfort in knowing you made her time on earth so much better.
I am so sorry for your loss. My deepest condolences to you and your family.
