I can reccomend some software that might help you make a visual novel on your own.
Ren'Py is completely free and fairly easy from what I've heard. Doki Doki Literature Club was actually made using it.
TyranoBuilder costs $14.99 but it's really easy to use and doesn't require any coding whatsoever.
I'd reccomend trying Ren'Py first, and if you find it too confusing or difficult you can buy the easier to use TyranoBuilder.
Hope that helps!
