Emptiness Leads to Depression

I'm feel empty and broken when I laugh it sounds like tears. And I have so many dark fears. When I smile it doesn't reach my eyes. And my world is surrounded by suffering and lies. When I feel useless in this life . I'm stare and wonder at sharp knife. I feel I'm empty and broken I don't know what to do, I can't do anything In my soul, there's no longer light. When I can't be happy anymore. I have a darkness in my own core. My soul is getting empty inside, and it's getting harder to hide, and I think I might just thinking, about suicide.
