It's the loneliest feeling in the world- To find yourself

It's the loneliest feeling in the world- 
To find yourself standing up when everyone else is sitting down. 
To have everyone look at you and say "what's the matter with her?"
I know what it feels like. 
Walking down an empty street, listening to the sound of your own footsteps. 
Shutters closed, blinds draw, doors locked against you. 
& you aren't sure whether you're walking towards something, or if you're just walking away.
