Similar to the article I linked to yesterday about males with depression not recognizing it, or being willing to talk about it being depression, this Psychology Today article also notes that what we think depression looks like, isn’t always what depression looks like.
“It may surprise readers that depression has many faces. Don’t be fooled by characters like Eeyore from Winnie the Pooh or Schleprock from the Flintstones. A lot of people are depressed and look nothing like these icons. Depression can also present as anger, irritability, opposition, and defiance, especially for children and adolescents, and especially males.”
Not everyone is going to mope around and talk about feeling sad. Some people, maybe even people in your own life, are going to just be kind of irritable, maybe even mean.
You might ordinarily call this sort of behavior “acting out”, but it could be so much more than that.
