Oh this picture of your inner demon looks like mine, if the demon is the chain and the girl is you. I have never thought of drawing my own demon, though. When I was depressed I saw it like an elusive entity that dragged me through a life I didn't like pulling me by my neck with a chain, while I just wanted to be let alone and rest, or go somewhere else.
Very beautiful and powerful image
My depression was always what held me back from the life I wanted, at its worst, taking away even the desire to do anything and leaving nothing left.
Nicely done, you captured the feeling beautifully!
