I do not know if this was demonic deliverance or not, but I do have something to share.
I have a severe and fairly rare mental illness called Schizoaffective Disorder. It is like having Bipolar and Schizophrenia without enough symptoms in each mental illness to be a diagnosis. It occurs in roughly .3% of the population.
I moved out of my parent's house when I was 32 or 33 (I forget) which was almost 5 years ago.
Due to my mental illness, I have struggled with paranoia. These are either haunting visions of terrible scary things or paranoid delusions I have experienced for most of my adult life (I am currently 38 years old).
I have found shortly after moving out of my parent's house, that these fear-based symptoms started to be less frequent. It is now at the point that I rarely if ever experience these horrifying experiences.
What was it that changed things? Well, it was in 2018 that my faith was confirmed. I mean I had the most amazing experience I have had in my entire life and this confirmed the Bible as the Word of God in a single conversation with a man who I can only call a prophet, I went from being a pantheist to being willing to die for my faith (long story, but you can read about it
here).
Since that time my faith has been confirmed, and I devoted myself to the Christian faith in a way I never had before then. I was raised in a Christian home and my parents are amazing people who tried to instill the faith in me since I came out of the womb. But I rebelled and became an atheist.
To make a long story short, as I devoted myself to prayer, reading the Bible more, studying theology and apologetics, and going to church, my paranoia started to dissipate. I have spent many sleepless nights awake due to this paranoia. Today, I cannot remember the last time I struggled with this paranoia. It is all due to the grace of God.
Is this spiritual deliverance from demons? IDK. What I do know is that God is healing my mind and I no longer struggle with these things as I did before.
