I think it's really prioritizing what you need to do. You can think of a lot of things you want to do but may not be as important as you make it out to be. Sure, making money is great on the sidelines, can't be wrong about that and one avenue is through writing, but don't confuse your passion for writing as money making because you can still write for no compensation and enjoy the task. It sounds like you write for money rather than writing for the sake of enjoying the writing process. If there was some other task that was more easy to do and pays well, would you honestly say you'll be spending more time worrying about not writing anything?
Your priority right now is being a student and while lessening the financial burdens during study for your folks is noble, it's not the primary objective. I got my primary job as a doctor, I enjoy shitposting more than my actual job but practically speaking, shitposting doesn't put food on the table and isn't a priority. That's my answer on what I should be bothered about instead of an online presence where my "brand" can only stick for 3 seconds and lost into the void of competing distractions.
