Perfectionism

The finicky and obsessive mind-set known as perfectionism "goes hand in hand with anxiety disorders," Winston says. "If you are constantly judging yourself or you have a lot of anticipatory anxiety about making mistakes or falling short of your standards, then you probably have an anxiety disorder."

Perfectionism is especially common in obsessive-compulsive disorder (OCD), which, like PTSD, has long been viewed as an anxiety disorder. "OCD can happen subtly, like in the case of somebody who can't get out of the house for three hours because their makeup has to be absolutely just right and they have to keep starting over," Winston says.
