Young adulthood is a minefield of mental and emotional trials whether you're entering the workforce (or getting laid off) for the first time, coming home from war or having your first child. Now's the time to monitor your mental health. The nonprofit organization Mental Health America has a 10-item checklist of tools for protecting and promoting your psychological well-being. Some are good old common sense: eat well, exercise, get enough sleep, foster good friendships. But being mindful of your mental state means recognizing when you need outside help. The National Institute of Mental Health is a good starting point for resources for people who may be battling depression, eating disorders, social anxiety, posttraumatic stress disorder and other conditions.
