6.7% of the US adult population, approximately 14.8 million, are depressed in a given year. While we think of someone with depression as sad, dirty, refusing to comb hair or bathe, or simply with a flat and emotionless face, this isn’t always the case. There are 3 uncommon depression symptoms that can be well-hidden in the corporate world. The information below isn’t meant to act as a diagnosis, but rather to help you identify if you (or someone you know) may need to consider seeing a professional for further evaluation.

Anger is a major symptom of depression that is uncommonly tossed to the side. People think anger is a sign of frustration at work when it really can be rooted in depressive feelings. Understanding why you are angry or what your true emotions are that are causing the anger can help you understand if you are truly frustrated at work or if you are depressed and that is causing you to feel anger.

Working too much is a sign of depression. Yes, throwing yourself into your work to avoid confronting why you feel down or glum is a very real symptom of depression. According to a recent piece on Forbes that did focus on this very topic, ” they cannot change about their life or in themselves so instead they immerse themselves in something they can do something about: work. It becomes a type of drug to distract oneself in the hopes that the despair will dissipate and they’ll eventually pull out of it.”  Are you working too much to avoid dealing with sadness or disappointment? Maybe feelings of not having control over one’s life?

Feeling burnt out. It is possible to get burnt out, but most of the time that feeling is really depression. It isn’t that you have worked too hard or that your kids have drove you to a place of exhaustion for the last time- it is that you feel things are so stuck in their ways that you resign to being burnt out- when, essentially, this is a heavy place of depression.

The workplace is challenging. Anger, working too much, feeling burnt out – those can be associated with a tough job, but they are all signs of depression too. If you are having these symptoms, it may be time to start considering seeking a professional evaluation.
