This happened to me when I was streaming. My favorite hobby became like a job. I only played while streaming and the time I was putting in outside of work was kind of killing me. Working a full day, coming home to do dinner and time with my wife and then start streaming by 8pm a couple days a week. It exhausted me. At some point I started to skip days and then I just never went back. Now I play games as a form of entertainment like watching Netflix/Hulu. I do it for leisure.
Sometimes I miss it though and think maybe I should try and get back into it but so far I've just not.
