Have you ever been alone in a crowd

Okay, so i was bored and i wrote this, the title is pretty self-explanatory.

Have you ever been in a crowded room
feeling as though you were the only one there?
Depression and anger creep up behind you;
Controlling your thoughts making your heart race.
Your eyes become fiery with all the rage of your life.
And the only one who can calm you down
Is the one person you don't want to see you like that.
You try to keep calm not let the one person know,
That the anger you feel is because you're alone
You wish they were here yet you wish they were gone.
No one should see you, no one should know
That you are, like all humans, simply an animal.
You can't admit that you are like them;
Another face in the crowd.
So like everyone, yet so singled out.
Have u ever......
Been alone in a crowd?
