It sounds like you're going from success to success, big career mistakes usually end in the unemployment office or at least a demotion. Your old coworker the director is probably making himself miserable because his cousin is a CTO and maybe that cousin went to high school with Elon Musk.

It's part of the human condition to feel jealousy, regret, inadequacy, etc. Definitely work on processing them, letting go of them, figuring out where they come from, but try not to beat yourself up for having them in the first place.
