Is it normal to feel like the most rotten creature alive?

Sometimes I hear my voice and I think it sounds groggy and then I see my brown skin and eyes and hair and I feel like walking poop since poop is brown too. Then I'm also very clumsy and shy and can't dance with any rhythm or ride a bike or swim. I guess lacking these skills makes me incompetent. Guess to avoid being annoying I should cut myself off from the human species since humans can be so whiny and complaining sometimes. Yeah, isolation rocks!
