Plotting My Downfall

In the unsure pain of my heart
I kept my pulse beating
Unsteady, unsure -
I was sick with worry,
Yet I had to go on.
Mediocre filth was all round me
Pressing its summary advantage;
People without purpose
Aimed at deflating my pride:
I was arrogant,
An upstart,
I had to be stopped;
I was ill-mannered,
A daredevil,
I had to be harangued.
Brash and uncouth
The users found me hard;
The oppressors and enviers waited -
All plotting my downfall.
