I have often asked the same questions.
One answer that is both devastating and liberating is -
I was not special in any way.
I was only available and vulnerable.
it could have been anyone.
It was not because I did or didn't do anything.
just the wrong place at the wrong time.
and I did nothing to cause or contribute to what happened.
I am off the hook.
Hope you can do the same for yourself.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
