overwhelmed

i feel like i am in a long, long pool and trying hard to swim to the end. i am running out of breath and even when i try to gasp for air, it would just take me a moment and i am struggling again. i could not stop swimming because then, i will drown. i have to keep on going. the end just seems so far ahead, i could not see it. i just tell myself, "breathe, swim, breathe". i know that when i reach the end of the pool, i would be so exhausted... wondering why i ever did start in the first place. i just hope that when it is over, i would also feel a sense of accomplishment and see the reason for it all.
