Even if you already have left, and won't read this, just don't give up.
It's hard to get recognized for what you do, like drawing or singing. People sometimes just can't recognize that others need more publicity because they work hard at what they do.
I almost gave up on my account as well, but then I got my first watcher. I didn't care if I got any more, and I didn't care if they deactivated their account. I was just happy to think that I was actually worth someone's time, and I just kept going on Deviantart. I felt like giving up and quitting Deviantart so many times, and people barely comment on my posts, either.
But I kept my head held high, and I actually like your account and what you make.
Just don't give up.
