When did it hit you that your career was gradually changing who you are?

I realized it when a friend asked what I had been doing lately and I had no answer. I was just working, coming home drained, and repeating the cycle. I had stopped making plans, abandoned my hobbies, and only ever talked about work stress. It happened so gradually that I didn't even notice until I couldn't remember the last time I felt like myself.

It took me much too long to realize it wasn't just a difficult phase; it was the job itself.

Has anyone else had that moment where you looked around and realized you barely recognized who you had become? At what point did you realize your career was fundamentally changing you?
