WATCH: Do you know what to do if your friend seems suicidal on Facebook

We know that social media helps us express ourselves and keeps us all connected. But we also know the internet can be an ugly, scary place. Do you know what to do if someone you know seems suicidal?

Now if you see an update from a friend that really makes you worry, Facebook has given its 1.65 billion users tools to reach out and help.

With the new features you can flag your friend's post and a team at Facebook will then advise you on how to communicate with them and give you information about suicide prevention.

U.S. suicide rates are at a 30 year high- especially among women and middle aged Americans. We lose more people to suicide than breast cancer, car accidents, and homicides] Last September, when President Obama declared a World Suicide Prevention Day, he called on people to recognize mental health issues early and to reach out to support one another.

Because 72% of Americans connect with their friends and family on Facebook, researchers on the suicide prevention project think the tool is a natural fit.

Let’s look out for each other. Online and off.
