How do you not feel jealous when you see the toxic people you worked with thriving together?

I left a company after an incredibly degrading 1.5 year period at the end of my 3 year tenure.

I was constantly talked down to, left out of conversations, work overlooked, and under resourced as a way to make things difficult for me and me only.

I performed very well despite it all and left when the slander and constant attacks felt unmanageable against an assortment of stress buildup in my personal life. It was an incredibly stressful time all around my life.

I worked with some of the most abrasive, condescending, and non collaborative people who I see celebrating their promotions, thanking each other, so full of positive wording and all, knowing how they treated me like shit and pushed me to quit while benefiting immensely from my work and time. I didn't want to leave, I had invested so much time and energy there, I wanted to work well with them, but I became the target.

I've done a lot since I left . I grown in many ways and have really built myself up, however I still find myself pissed off and ruminating over my time with people who probably don't even remember me after all that shit. Me leaving was just good riddance.

How do I let go? I feel like I need to move to the other side of the country and start over. I hate where I live. The chances of running into someone is near zero, but I feel too tied to that period.
