A break sounds good! I know how it feels to get so stressed out about a video game, it loses all the fun! Hope you can come back to it and have fun again
Maybe if I'll come back to this game, I'll just design and share clothes I make and possibly turn my town into a cycle town so I won't fuss over town layouts and getting attached to my villagers. It's too early for me to decide what to do in case I want to get back anyway. But I think I wouldn't be touching this game for 5 years until and I get all the Amiibo Cards of the villagers I want to include in my town.
Switching into other video games is what I've been doing now. Right now, I've resumed my Harvest Moon: The Lost Valley game and restarted my Animal Parade game in the computer. I might eventually give either Population Growing or City Folk a shot, if I have enough time and if my computer can still handle emulating more games.
