A mental illness is a disorder that affects moods, thinking, and behavior and requires management through treatment and/or therapy. A mental illness can come from abuse, trauma, brain chemistry, continuous exposure to stress, and/or a family history of mental illness. It can occur from time to time or be chronic – something you have to live with.

A mental illness does not suggest that one is “crazy” or that there’s something wrong with them. It’s not one’s doing or wish to have a mental illness – life happens and just like any other disease, mental illnesses are manageable. They are more common than you’d think:

  • 1 in 5 U.S adults experience a mental illness each year
  • 1 in 20 U.S adults experience a serious mental illness each year
  • 1 in 6 U.S youth aged 6 to 17 experience a mental health illness each year
  • 50% of all lifetime mental illnesses begin by 14, and 75% by age 24


Mental Illnesses Are Not Adjectives

To end the stigma surrounding mental illnesses, we must start by not taking them for granted or treating them jokingly. Behind our everyday common use of mental illnesses as parts of speech, lies people who are actually struggling to manage and get by because they’ve been diagnosed with a mental disorder. Still don’t know what I mean? Have you heard anyone say the following?

  • You are acting so psycho/schizo
  • I am so OCD – I keep everything neat
  • You look so anorexic
  • This movie is so depressing
  • I swear I feel so retarded
  • She’s acting so mental right now
  • You’re behaving so bipolar
  • I’m going to kill myself if this doesn’t work out
  • I am so ADHD today – I can’t seem to focus on anything
  • You almost gave me a panic attack


These are just some of the phrases people use to describe people or situations and it’s often in a negative light. This in turn propels the stigma and makes us treat mental illnesses as a bad thing or not take them as seriously as we should. In the same breath;

  • Depression is more than just sadness
  • Anxiety is more than worrying
  • OCD is more than being tidy
  • PTSD is more than just flashbacks
  • Bipolar is more than just mood swings
  • Eating disorders are more than just being underweight
  • Borderline personality disorders are more than just instability
  • Addiction is more than just a choice
  • Schizophrenia is more than just seeing things.


So, what exactly are these mental illnesses? This list is curated from the Diagnostic and Statistical Manual of Mental Disorders (DSM) handbook that is used by American clinicians and psychiatrists. It’s published by the American Psychiatric Association (APA). Mental illnesses are so many, we can’t cover them all in one blog post.
