Sorry to hear that you are having a tough time.
But that is not how it works. Building an account that makes posts that are "worth your time", takes time. Years in fact.
I have a group where I record their weekly growth. Your posts do well for an account only 2 months old.
You need to build more connections. Which is something I see that is lacking on your account. Engagement. You need to answer all comments on your posts. Start conversations.
You should also go make comments on other people's blogs. There are people on here who post very simple things in comparison to your art and those posts earn more too. The difference is that they engage more with others and have grown alongside those people.
Thank you very much. I replied to your comment elsewhere. Because you posted it twice.
