Well, your depression may need something new to chew on, because the insecurities about your art deserve to have those hurts healed & I think a lot of people are going to love your style.
You're fantastic! When I've had my interest in Steemit wane, your Slothicorn illustrations always pull me back in. They're very marketable & would be great as merch, stickers, a coloring book, or children's book characters so I think your dreams are on track.
I'm sorry you're family hasn't supported your art, but I'm so glad you're here.
(I can't wait for someone with pull to discover you.)
