@babyportgas I get it. I get disheartened with the lack of interaction on my own stuff too. In everyone else's defense regarding mine, I'm currently just posting theories instead of stories.
Wattpad does provide a uniquely golden opportunity in that readers can interact with authors directly. I see two ways to look at the lack of interaction, and I hope one of these ways will help you. The first way to look at this, is that it's nothing you've done but it is still the readers' loss.
They are letting a golden opportunity to interact with an author slip through their fingers like grains of sand. How many of us would kill to be able to post comments on each paragraph of our favorite authors that we grew up on or read in school? And here these readers are, letting you pass them by. They're the ones missing out, not you. You're not writing for those buffoons.
The second way to look at it, and I think this may be the predominant case, is that the readers suffer from a similar anxiety to you. You get anxious to the point of not wanting to write. What if your readers got anxious to the point of not wanting to comment?
There have been times where I don't comment because I'm afraid I'm leaving too many notifications for the poor author (like for Quinloki), or I'm afraid my opinion is too niche and no one will like it (like my favoritism of Arlong or my strong dislike for Usopp & Nami).
Sometimes, I'm just not comfortable commenting on large portions of writing because it's something I skim (I actually skim the lemony bits no matter who wrote it). The readers might be nervous or scared or anxious or uncomfortable. Maybe voting is the best some of them can do or just reading to give you views.
No matter the reason for why they have or have not interacted, the number one rule of writing is to write for YOURSELF. Write the stories you want to read, alter the canon the way you want it to be. Write for you first & hopefully that helps with anxiety the best.
