I am a person who has spent his whole life running...

Running away from my fears,

Running away from responsibilities,

Running away from things that I hate,

Running away from people that I love.

But it is only now,

As exhaustion overtakes me

And I can run no more,

I find the only thing I have in fact been running from

Is myself?

hmmm, maybe try "walking away" gives you more time to stop and change directions.
