Alright, I'll do this in two parts. First off I'll give some general advice on writing and then I'll talk about your specific situation. Because those two are definitely different conversations.
First, for the general advice. Ironically, the first step to writing something original is to read a ton of stuff from other authors.
What genres are you interested in? Which do you like reading and which do you like writing? Pick one and immerse yourself in it. Fifty to a hundred novels should be enough to "get" a genre.
Why does that matter? Because your ideas can only be novel when you know what has already been done. The worst example of what can happen if you don't do that is the game Tales of Zestiria, which had the bold idea of "What if Hero versus Dark Lord BUT WITH A TWIST" without realizing that even the deconstruction of "Hero versus Dark Lord" has been done to death already, so all their thrilling new ideas had also been done before.
Also, don't force it out. Read, read and read some more, until your own story starts crystallizing in your mind. And once you can no longer enjoy other people's work without thinking about your own story, then you should start writing.
There, that was the general advice. Now for your case specifically.
Stop spamming chapters. Building a readerbase takes time. Like, that story you're still updating, Duty, Empty Dreams and Trying Not to Become a Monster.
8.6k views and you've only been properly publishing that for a month. That's amazing. Now, what drove you to spam chapters at that speed? Pace them out so that people actually have a chance to read it. Having an "upload day" every week gives both you and your readers something to look forward to.
It feels like your problem isn't so much that you don't have ideas but that you want instant gratification and feedback and writing is an absolutely terrible hobby for that. Reading takes time. Reading the literal novel (77k words) that you've chucked out within a month takes a lot of time. And until people have properly digested that you can't expect them to click that little "Read" button.
And also, if your story isn't extremely light novel-esque and filled with smut you will never see the kind of ludicrously fast reader gain that you seem to be wanting so manage your expectations.
tl;dr: Stop being so hard on yourself, you're doing great. You only need to give it time.
