Help Me. Give Blood.

Its aggravating,
Irritating,
To the point of disorientation
Everywhere, every spare
Piece of wall
I see "Please give blood".
They scream and call,
Blame you by name
to give your blood. 
If you don't,
Then its wont
They'll put you to shame.
Its a blame game,
A dice of infaliable guilt-trips
The blood, the dying children,
Eyes of pity
Crying for you to
Spill your blood.
All over, everywhere,
Constantly, constantly, constantly...
Yet they never know,
Because they never ask:
They just blame,
For
I am not appropriate
There are rules upon laws
Drug abuse and tattoos,
And the cincher,
The unfortunate,
The absolute minimum
You have to be a certain weight
to give out free blood. 
And
How can I be if I am small?
