I've found there are two main types of people with depression: those who show outward signs of depression (look like they're depressed) and those who internalize it (look like any other person on the street). Obviously you can fluctuate between the two but it seems like most people are primarily in one state or the other.

Most people don't know when I'm depressed because I keep it all inside until I'm alone at home. If they know something's up, they usually just assume I'm tired.

What about you guys?
