Perhaps one of the most helpful things you can do if you have a friend or family member who struggles with depression is to help guide them toward healthier eating and lifestyle habits, as making changes can be particularly difficult when you're feeling blue — or worse, suicidal.

If you are feeling desperate or have any thoughts of suicide, please call the National Suicide Prevention Lifeline, a toll-free number: (800) 273-TALK (8255), or call 911, or simply go to your nearest hospital emergency department. You cannot make long-term plans for lifestyle changes when you are in the middle of a crisis.
