I tend to work with addicts, alcoholics, abusers, and abuse victims. Often, others are not quite sure what some of the typical symptoms are of some of the most common mental illnesses. I decided to make my life a little easier so I typed up a little “cheat sheet” with descriptions of some of the most prevalent mental illnesses I come across, particularly when dealing with substance abusers. This list is by no means exhaustive. The definitions were taken from the DSM-V.
