Nice drawing and all, but a sceptic will just see a picture of a depressed or anxious person. What is it that's been made visible exactly, a sad face?
Before I opened the thread I was expecting to see something more dramatic; a spine that was on fire, a bed made of barbed wire, clothing made of chains, a vice around the chest, a heart squeezed in a mailed fist, acid being poured through veins, medieval torture implements on the head and so on. I would do it myself if I could still draw. Think Frida Kahlo's metaphors for physical pain.
It's the bodily, organicity of the disease that needs expressed, not unhappiness or a vague feeling, since it seems most people out there can't tell the difference from tiredness/depression/worry etc.
