Fallen Soldier

I was once a soldier, Always standing tall. Going through my problems, I would never fall. But every now and then, Something comes along. It makes us feel so weak, Makes us not so strong. I've felt the torture, I've gone through pain. I've gone through the things, That sends people insane. I've gone through hell, And I bounced right back. I've been to the dark side, Where everything is black. But this time, I'm left in the gutter. No-one sees my pain. And no-one sees me suffer I smile on the outside, I'm screaming on the in. How do I show my pain? Where do I begin?
