1) It sounds like you have a decent amount of negativity built up from your previous role, and you haven't quite vented it all out. Get it out of your system -- talk to a friend that gets how annoying that was and vent until you're tired of talking about it. Get heard and you'll feel like the negativity is finally behind you.

2) Think about the opportunities that your previous job gave you. Specifically opportunities. Every time a negative thought comes up, ask "What was my opportunity at that moment?" and write down your answer. Opportunity to disagree and commit? Great. Opportunity to solidify your understanding of your own values? Great! Opportunity to challenge yourself and work on something outside of your comfort zone? etc. Write those down and brag about them to your next amazing job!
