Ultimately the decision is yours.
I can understand that sometimes you just need a break, and it’s not in our power to make you stay, I wouldn’t force you to stay if it meant you were constantly feeling burned out or depressed, I mean I quit the app like 2 years ago and hey I came back, and I’ve been posting ever since, if you feel like you need some time, then take all the time you need, and even if we aren’t here when you get back, there are still plenty of people who would love to see your artwork.
