Have you ever lost something that you know you don't need but you want it so much it makes you sick to see other people with it?
(This goes for losing someONE as well)
You feel like you want to kill whoever has what you "need."
But then again, you know there's no reason, because whatever/whoever it was has moved on and left you sitting there still completely consumed in thoughts about your loss.
Even after you move on from those thoughts, after you get over the "needing," the jealousy still remains...
So while your "need" is gone forever, without a care about you, you still sit in the middle of your thoughts.
And during the time they will find their own need, and probably lose it as well.
Funny how things work, isn't it?
