The concept of self-harm is alarming, particularly since 90 percent of those who are engaging in self-harm are adolescents or younger. It's estimated that 38 percent of young adults and adolescents are participating in self-harm, and 40 percent of college students admit to doing it over the age of 17.

They might stick objects into their skin, burn themselves, intentionally break their own bones or bang their heads against the wall repeatedly. Self-harm is often the sign of a psychological disorder, and many disorders that include self-harm occur alongside each other, such as bipolar disorder, PTSD, schizophrenia and other major depressive disorders.

More than 6 percent of high school students admit to attempting suicide, and an equally alarming 14.5 percent say to have considered it. Some reasons for self-harm can include creating a sensation, self-punishment and using it as a coping strategy.
