Suicide is on the rise. According to the CDC, there's been a 30% rise in suicides since 1999. What can we do to prevent it? First we need to look at what’s causing it.

Many factors contribute to suicide and surprisingly, a history of mental issues is not always one of them. In fact, a recent study from the CDC found that 54 percent of the people who killed themselves didn't have a previously known mental health issue; rather, they were dealing with other problems including substance abuse or physical health, relationship, work or money issues.

The study emphasizes the need to both prevent the circumstances associated with the onset of emotional issues and to continue support those with known mental health issues. The authors of the study stress the need for prevention, which includes “teaching coping and problem-solving skills to manage everyday stressors and prevent future relationship problems, especially early in life; promoting social connectedness to increase a sense of belonging and access to informational, tangible, emotional, and social support.”

So what are some warning signs of suicide?

According to the US Dept of Health & Human Services, here are 11 suicide warning signs:
