|1.||To die a little|
The best way I can describe this feeling, is like having a part of your soul (or heart) just stripped away without warning.
It can be seen as jealously, but that's the pessimistic view. If you can admit when this has happened to you, I call it just keeping it real.
When your immoral slut friend or cousin or just some ugo in general gets married before you, that might cause you to die a little inside.
When your friend gets that promotion that you secretly wanted, you might die a little inside.
When someone preferred your prissy and pretentious neighbor's sweet potato pie over yours, you might die a little inside.
When you see your ex with another person so soon after you, you might die a little inside.
"Every time a friend succeeds, I die a little."
