Your situation is is very similar to how mine was. I recently changed jobs after being on the same team for almost a decade.

It's honestly a bit rough having to rebuild relationships. I'm working in completely new technologies, which is one of the reasons I decided to move, but it's kind of difficult to go from a place of 100% trust of your peers to uncertainty about how they perceive you.

I've still been seeing some of my old team on weekends.
