I'm so sorry you see things this way. I just left my job after many years at the company, and while my goal wasn't to make friends I definitely ended up collecting a few along the way. I was in upper management and definitely cared about my team, and so did the directors under me. I befriended some of the people in the C-suite as well. They threw a nice, big surprise going away dinner for me, which they definitely didn't need to do. I've met up with former coworkers in other departments to catch up, because we genuinely enjoy each other's company. I hope you find a place that values you and that you can find a friend or two that you can keep in your life.
