You are

the Doctor,

flying through time and space

in your little blue box

that's not-so-little

on the inside.

You've had many friends-

companions-

over the course

of your adventures

but

something always

goes wrong

and

they leave you,

or you

leave them.

And there are

gaps of time

when you are

alone and

it eats you up

because

in the silence

you can hear

your memories clamoring,

shouting for your attention

and you do not

want to hear them.

So you

continue on,

running from your past

though you always

tell yourself

you aren't

and some days

you believe it.

But the truth

is always there

lurking

in the back of your mind

like a hungry

predator.

So you keep running

and tell yourself you aren't,

because

admitting you are

is the first step

to facing

your deepest fears

and staring in the face

all your mistakes,

all the times you've been wrong

all the faces you've lost

all the wrongs you've done

and you are afraid

that they will swallow you whole

if you try.

So you don't.
