If you want to be a victim, you can be. Forever.
Being a victim sucks. I should know. Been there, done that. If I no longer bear visible emotional scars, it is only because I did something about them.
It doesn't matter what your employer did to you. You aren't there any more. You are living your life. And right now the only one who is doing you injury is you.
If you need help getting out of your pit, I would strongly suggest (based on the experience of friends) swallowing your pride and getting a Prozac prescription. Certainly it will do more good than complaining, again, about people you aren't dealing with any more.
Cheers,
Ben
