Sharing my situation, maybe it will give TS different perspective.

I tendered my resignation after decades of being in the same organization - because I don't see eye to eye with my superior. The reason I've stayed on is that I enjoy working with the next level boss whom I respect - the same boss who asked me to stay after I voiced my intention to leave but also the same boss who refused my request to transfer to another unit.

I'm worried about job opportunities after I handed that piece of paper. I also know I will miss the opportunities of working with the same boss.

Yet I also know I want my working life / environment to be something I enjoy and happy mentally in order to be productive, creative and healthy.

Good luck TS!
