Why?

Sometimes it's a fine day.
Nothing bad. Nothing good.
But inside I'm not okay.
Inside I'm screaming.
Inside I'm crying until the tears do come out.
Inside I beg for help.
Outside I smile.
Inside I overthink everything.
Outside I smile.
Inside I feel alone.
Outside I'm not.
Inside I'm broken.
Inside I'm broken and angry.
Inside I'm broken and sad.
Inside I'm not me. But I am.
And all that's left to say is
Why?
