Best quess out of 100

It will ask you why you walked away.
And you'll say something to spare the truth, and it's feelings.
Thank you sssssooooooo much.
Without you it still breaths, but more labored.
I hope this was not in vain,
but don't we all.
Grusome task this becomes,
untangling what we've become intangled.
Once the hacking starts,
the blood will not stop,
until it's gone, along with memory.
