I have no interest

This parasite has taken over.
It controls my very being.
No longer the strong vessel I once was,
yet it still demands more.

more sacrifice,
more pain then I can endure.

I have given it everything.
My food,
My spare time in order to burn off calories that I no longer consume,
My health,
My life.

I have no interest in denying this parasite the things it wants though.
For I would be nowhere without it.
I would not know how to go on.

How am I going on?
I have lost so much weight that my clothes no longer fit.
It is always cold,
even in the summer.
My skin is so thin and my eyes seem dull and hallow.

Yet despite my physical decay,
I feel more alive than ever.

I have no interest.
I have no interest in quitting this just yet.
