Yesterday's today

I made a mistake,  why can't I move on?
Why do I sit in my past and stew over my wrongs?
I asked for forgiveness and repented in ever way, yet my past still haunts me to this very day.
Is there any way for me to forgive myself?

I keep replaying over and over in my head, what I could have done, what I should have said.
I pled with God to release my bind from the demonic presence that controls my mind.
One day, I'm happy believing in brighter days, feeling hopeful about the progress I've already made.
The next day, darkness overcomes my soul,
Whispering my mistakes that put me in this deep hole.
Why is it so hard to forgive myself? Why won't my past leave me alone?
Why can't I be happy with life and allow myself to grow?
Why do I judge myself for things years ago?

why do I allow myself to become all alone?
Why do I allow my demons to torment me for a past I no longer own?
Why do I blame myself for the actions of those I loved?
Why do I blame myself for not seeing the truth for what it was?
Why do I blame today for yesterday's mistakes?
How do I remove myself from the place I so often sit?
How can I move forward when today's yesterday's reminisce?
How do I become myself when I am reliving yesterday's abyss?
How am I to be me when yesterday is my today's present?
