Poem?

They say to me that I’m their friend;
I’d like to say they’re not so wrong.
Yet even so, with such support,
I really know I don’t belong.

When the world fades away at night,
Do I know who’s really there?
I may know as many as stars can I count,
But a true friend is ever rare.

Is anyone really there for us?
Is the world so bleak, so cold?
So oft a story forever silenced,
Its contents remaining untold.

By such thin threads do my friendships hang;
So easily they could be severed.
But how much do they really mean?
Are they truly to be treasured?
