What wild ideas always comes to them?I can't imagine how terrible they are! I don't know how to be monstrous to them? I already suffered an ache over my larynx.. it's really painful after shouting at them, I have given them my full voice and my nerves almost comes out... but still I became a loser...I can't be able to achieve what I really want?hope God will help me with this?
