I recently found an article called, 12 Common Symptoms Of Depression That Shouldn’t Be Ignored. Click the link and read the whole article but here are the bullet points.

You’re always tired
Everyone and everything annoys you.
You sleep too little or too much.
Eating’s an issue.
You’re in pain everywhere – pain can make you depressed, and depression can make you feel pain.
You don’t care that you look messy.
You’re hiding.
Nothing interests you.
You’re beating yourself up.
You’re forgetful or have trouble concentrating.
You feel numb.
You think about dying.

If you or someone you know is showing more than one of these signs for an extended period of time, please enlist the aid of professional help.
