@Callaxes, I don't have much experience in overcoming break ups, but I can tell that Inktober and other activities that keeps you from thinking too much about bad experiences we just came through helps a lot. In 2013 I had just lost my job and focusing on Inktober helped mea lot to handle things. I hope you get better soon!
Here's my enter for Inktober 4th. Still developing things for my personal project.
