Inktober is a relatively new month-long challenge for artists all over the world. It was created by Jake Parker, who came up with the idea to focus on improving skill and developing positive drawing habits. For 31 days of October, everyone who wants to participate creates an ink drawing and posts it online using the #inktober tag. Each year there's a new prompt list to be used for the pictures. Shawn Coss decided to ditch the guidelines and create with a theme he felt more sore to him, posting new mental illness ink depictions every day of the Inktober.

Shawn's mental illness art translates sicknesses of the mind in an eerily accurate way, and his ghoulish illustrations don't end with Inktober. The artist has worked for such clients as the horror king Stephen King himself, creates Cyanide & Happiness cartoons and even has his own clothing line.

So if you're searching for support with your mental illness or are plainly into horror, check Shawn's art below. It surely gave us the chills!
