Writer's folly - The tendency to overthink

Hello guys!

Freshly joined the subreddit as I feel an extensive invisible weight on my shoulders and have to share it somewhere. This is the place where I hoped to be understood best.

Disclaimer: This is going to be mostly me rambling. I don't want to take up the precious time you lot have to write, so continue on your own discretion.

Currently, I finished two chapters into book 2 o a story I am writing. This is the first time I had ever managed to continue with a project post book 1. With that, came the heebie-jeebies.

As one of my followers (of which I have 36 on R&R currently, I know amateur) stopped following me right when I posted the first new chapter. I know that this is bound to happen and I should not make it a big deal, but it lead me to a spiral of doubt and feelings of inferiority that had long passed the stage where I am able to control them.

I have zero to no feedback on the story as a whole, comments are scarce and are not critical at all. The three reviews I've gotten are nice, praising me quite a bit, which leads me to think that its just very nice readers, trying to boost the confidence of the writer.

All in all, it leads to the question: Do you have any ways of dealing with such feelings?

I have not let it slow me down in my writing. I am bent on finishing this story, even if it might end up with less following than it started with. But I don't want this to blind me enough, to make me push out worse, unconfident story.
