I Do Not Like People to See Me Cry

I feel there is a line where people can see me cry. When I stub my toe, laugh myself to tears, or fall to the ground because I trip...yes, you may see me cry. Because those tears are most likely a reflex to the pain shooting up my leg, or the fact that I'm laughing too hard to breathe.

However, once that line is crossed, then the tears are for myself. They only show themselves when I'm alone.

The tears that flow with self loathing.
The tears that come within the well of my soul with overflowing sadness when happiness is torn away for the afterlife.
The tears of desperation.
The tears of loneliness.
The tears of fear.
