They push you down like a bag full of air in a pool full of water.
Best line in teh whole poem "But" is doesn't make since you see with all the preassure the bag should resuface no matter what holding it down. With a line like that the poem should be called a break though of the preassure. Not a with hold.
And that shell your so talking about, that not real you? ..
That shell is for protection, even Jesus cried in his hard times. =3
