i have this song i've been trying to write for a while now but i can't get the lines to work right. nor can i figure out one more verse

crit this please. i want serious scrutiny of this. if you have any way to make the words fit better or ideas of lines or something. anything. i want to get this done

chorus:
I’m sure the other me is crazy
Because I know that I am sane
We are each a different person
Yet we both live in my brain
And every time he comes around
I turn into something that I hate
I’m crying out in desperation
But fearing help will come too late

verses:
The love and care inside me is hidden
By the fury on my face
One moment mad, another sad
Once one is gone another takes its place

I’m holding myself hostage
Though I struggle all I can
Its so hard to fight the opposition
When you and your enemy are the same man
