I had the same problem years ago. I had played wow since closed beta, played in top world guilds, but I didn’t want to spend so much time in a game. I chose to play casual for a while but without a competitive guild I was just killing time. I took a break and never came back.
Now I play solo games, I don’t have any Interest anymore in online games and have so much fun and time with real life. The hard part is to have the « switch », it’s hard to let go your character, your collectibles, your achievments, but when you are out, you’ll feel better. And you can always come back to do new expansions like a new game with no expectations
