It's only me inside my mind

I'm in two minds.
The rational and the insane.
Both fight for control of my actions,
I fear I'll do something stupid,
like hurt someone close,
or maybe more than likely myself.
I can't figure out what's for the best
and it may be too late for sorry when this is all over.
I cannot have it both ways,
There's a word for people who do.
And I am not like that.
(yes you are)
I am NOT.
(but you are)
Please don’t let me do this.
(it's in your nature, take what you want)
But I'll lose everything.
(he'll never know)
I'll lose everything.
