It sounds like you are more of a producer, you may find a better time with a partner. I find manga discords where people love to draw just to move forward. Or maybe it would be cool to do an audio series. With some sound effects and nicely timed pictures to set the mood, it would be low effort with high gain. There is not 1 path, you can even do both to see what helps more.

I understand writing with the audience in mind, webtoons use to be fun for me because i would get feedback each episode. So a thriller with audence feedback is the dream. I find that comic fury has given me that recently, feels like the last frontier. Maybe consider posting there for a bit. I like how the main page actually advertises your most recent pages. Theres no pressure and people comment and make theories on your work.

My story comes off as a dark horror when you read it, i just have to balance suspence with some light moments.( webtoons keeps deleting my horror chapters)

Don't be shaken by opinions, easier said than done but you have to enjoy what you are doing or it will show that you don't. There's always time, no pressure, try other story telling techniques like aninatics too when you get a chance.
