What's the most emotional pain you've ever had?

Finding out 'friends' aren't true friends is a very unpleasant experience. But I think being lead on has caused me the worst emotional pain.

When my sister was murdered... She was my only sibling I actually loved, and at the time my only true friend.

When I think of my bf would leave me forever

When my marriage broke down...

when my daughter died

I don't even know.

it's a long story :/

shame.
