I Fake Smile To Hide My Sadness

Feels as though most day i'm just going through the motions. Ever notice that the sadder you feel the more everyone around you seems to come across as being happier? You just can't help but wonder where you went wrong or what you did to feel the way you do. Most days it takes all I can do to make it through the day. And no one seems to care either. Friends, family, etc...just act as though i'm an inconvenience, or they don't understand the depression and sadness I have.
