I think the hardest part about being a content creator is not comparing yourself to others. A lot of people here are young and young folk like instant results (I was young once, so please don't yell at me for saying this).
I can feel for everyone in this thread. It's so hard to leverage your own success when others are doing seemingly very well in terms of views/subs/whatever. I can tell you, these 'quick rides', are not quick. They are usually people with a high following elsewhere or they work extremely hard to deliver content, improve their art, engage, market themselves... Maybe like 1% will get popular due to sheer luck, but again, you just can't compare yourself to them. It just brings you down and it's not a realistic way to gauge your own success.
It's hard to believe, but to someone, you are not invisible. Though they might not sub and may not comment, but there is someone out there that thinks your stuff is great and visits it often. But most importantly, you should be making the comic for yourself. I know people here want to make money with their work or just get validation that their stuff is great because of views/subs, but if you feel like you're making your comic for 'no one', not even yourself, then you should stop. If you're not making the comic for you, then why bother? If you don't like your own work, it's going to get tiring very fast and burn you out because your mindset isn't in the right place.
Be patient and keep posting. Others will notice and are already noticing.
