To clarify this more so I don't sound like a complete psychopath:
I don't remember if this happened any earlier that this but I do remember in my late teens, around the same time my PTSD symptoms flared up for the first time, I started suffering from intrusive thoughts and fears. They caused me so much distress, they made me feel like I was dirty and messed up. I figured I must have these thoughts because of all the abuse I had suffered. So from then on, I did all I could to get rid of them. I would try to think of something nice instead, keep myself very busy and preoccupied all the time or pray to God or read a scripture or try to focus on the fruitages of the holy spirit. What gave me hope was knowing that I didn't want these thoughts in my head so they did not represent me, they must be as a result of abuse I endured.
So I never told anyone about these intrusive thoughts and I figured I would just do everything I can to forget them. Because I became a very religious Jehovah's Witness and that ended up occupying much of my time, the thoughts were under control and eventually no longer bother me and instead of me feeling like something is terribly wrong with me, the more "spiritual" I became, the better I felt about myself.
But that one day, that I reacted weird to trying to stop obsessing about this guy I liked and move on, I sabotaged myself by thinking a sick thought on purpose to push God's holy spirit away from me and I have not been OK ever since.
I even made my situation even worse and unbearable by confessing this thought to two elders in my congregation. Doing that didn't make me feel any better though and from then on, I started making dumb obnoxious decisions with my life that only made me feel worse and from then on, I felt there was nothing that could ever make me feel better so I got to the point where I felt I could not live with myself and just wanted to die.
