What are you expecting them to do about it? They have zero control over the content of their app so they literally can't do anything about it.
I do see it comes up under popular comedy when I search that on the website, so it still is there on the website. Again, they have zero control over the content on their app so nothing can be done about that.
I do think you're really undervaluing it. Art being aesthetically pleasing isn't just about having perfect details, proportions and backgrounds. Aesthetically pleasing art has unique character, mass appeal and refinement. Your art has all of these things. Only you can draw it. Meanwhile, you can compare to my art where I strive for perfection but it's pretty typical manga style stuff. I have spent many years on my art yet my following and appeal don't compare to someone like Sarah's Scribbles because it doesn't have those latter qualities.
This is spot on. I have a close family member who struggles with depression and it's painful and frustrating to be someone on the sidelines who literally can't do anything to help them. I can say when I look at my old art, yes, sometimes I will feel a twinge when I look at it and see how off some things will look. But it isn't normal to get so sick when looking at it, at least from my perspective. Maybe this is a symptom from your depression, maybe not. We're random people on a forum, we can't speak for your inner thoughts. But maybe you can change the way you look through your art to lessen that sickness you feel or to avoid it completely. Maybe it is that you stop looking at whatever you just drew and only focus on completely new things. I don't know.
Honestly, it seems like there's a lot of justifications being made in your mind for everything someone says here so I am sure you'll say "No, no, I can't do that" or some excuse. In that case, the discussion may as well end since nothing anybody says here will be any help in any way.
Only YOU can change. Nothing anybody says here is going to change you. If your end goal is to change at least. It really doesn't seem like there is a want to change here though. But again, it's your choice. Only you can want to change.
