Depressed

I know that i might seem a little negitive sometimes, but I am not depressed in any way. I like the negative way to think, but I won't act on it. And just because when i'm sick and its pollen season, doesn't mean i'm depressed. My mom had brought this up when she sa i wasn't feeling good, but illness is not a sign of depression, is it? But the point is my way of thinking, or the fact that i'm tired after going to school and walking home while i'm sick, should not lead anyone to think i'm depressed.
