Insanity

I'm thinking of a word
Oh what was it
It's a special little word
That's not it

Confusing it is
Decieving it be,
Obstructing in nature
conflicting in matter

What could it be
I wish I knew
so simply
I could feel

On the tip of my tongue
it rests right there
the word it is
what a scare

Oh yes I know now
what it is in it's entirety
I believe the word to be
My Sanity

Boy it's here
and just as fast it's gone
sanity here, sanity there
where did you go, you one little word

Sanity, insanity, what difference does it make?
Personality, characteristics, mental state

Are they all affected by this word?
Are they changed and morphed
Whos to know? who's to see,
Insanity
