Scratching at the surface now...

It's a continual scrape at my chest as my heart shivers violently.
I'm scared, to tell you the truth.
I'm scared of what lies ahead and I feel like breaking down.
I don't want it anymore,
I just crave to escape it.
May be I'll keep running away from one city to the next,
Till I find solace and some breath.
There's a throbbing pain at my head;
Something's prodding from underneath my bone.
I can withstand it for now,
But the way I see it ending is
Me falling into the sea
And not being able to shout for help;
May be I don't want help.
That shall be my goodbye.
