Honestly it sounds like you’re spread too thin. I would pull back on the platforms you’re finding less engagement on and focus on the places where your demographic seems most engaged. For example if your focus is video games, put more of your energy into Discord, Twitch, and YouTube, and pull back on Instagram and Tiktok. But I don’t know your specific numbers so use your own judgement on which ones are worth it.

Most of the creators I enjoy have other accounts, and while those might be fun, if their work suffers where it matters that’s going to be much more noticeable. Take care of yourself and really narrow in on the career you want and what you want to be known for. Good luck!
