Yes, I had the same thing. Constant lack of sleep, following the audience... It was all just incredibly hard. And not so long ago I found this service: https://soclikes.com/buy-instagram-followers And I realized how much it was all for nothing. Although of course strange to say it, because I started Instagram exactly 8 years ago, when such services did not exist, but still a little hurt.
I don't think it's necessary to chase subscribers. They feel it. I think instagram should be done with love and only because you WANT to do it. In general, this applies to absolutely any business.
