So you do have choices ... years down the road your interested in revenge? Seems like such a waste of energy to be honest. Okay you got hurt.. maybe that is what triggered your depression , most likely it would have emerged at some point over something that didn't go the way you hoped anyway.

It's okay to be angry , it's okay to throw a huge fit, maybe writing her and them a letter and saying everything you think about them and their actions, get it all on paper and then burn it , let it go .. maybe by just venting on here it will help you to move forward to reclaim the life you left behind , its never to late to stand up and dust yourself off and get on with making your life enjoyable and happy.

The thing is .. it's 6 years later, I seriously doubt they can even remember what they said or did to you. I'm NOT dismissing your feelings , I'm just showing you that this hate your holding onto is just keeping you down. No amount of revenge is going to make you feel any better. The only thing that is going to make you feel better is getting back into the world taking back your life and finding happiness. Living in the past removes any chance of a healthy future.

Everyone gets dumped , everyone gets picked on or bullied , its just part of life sadly enough.

Good luck with whatever you decide to do.
