Hi @Movingon83, I am sorry you are going through this but can totally relate to it as my mind was like yours when I finally got the courage to leave my emotionally abusive marriage. Twenty odd years of passive aggression, manipulation and gaslighting left me as confused as someone who had just walked away from an explosion. I couldn't get my thoughts straight, constantly changing my mind, second guessing myself. At the time I also had no idea that I had been emotionally abused as I was suffering with Stockholm syndrome and felt dreadfully guilty even thinking critical thoughts of my ex husband. I couldn't see the wood for the trees and drove myself insane with my whirring thoughts.
But I have recovered and thrived by entering into long term therapy. It wasn't pretty and I cried a river getting out all the experiences from my toxic marriage and my equally toxic childhood. You sound like you are suffering from anxiety with these racing thoughts of yours. Having someone listen to you in a safe environment is both cathartic and soothing.
I took up yoga. Best method ever of controlling your breathing and by association your anxiety and thoughts.
I took up meditation using an App. Made a habit of ten minutes every lunchtime.
Walked my dogs in the countryside, all weather's. Again nature and fresh air gets the feel good hormones going. Exercise another good one.
I did jigsaw puzzles, colouring books, quilting - anything that focuses the mind on what you are doing rather than thinking.
I took up some interests I hadn't tried before - creative writing, journaling, drawing etc.
I kept away from people who were not helpful to my recovery including mutual 'friends' that were manipulated against me by my ex. Drew a safe circle around myself and withdrew from the chatter.
It has been a long process but I have got there. I hope that I can give you some tips with my experience. I forced myself sometimes to do things even if inside I felt like dying. It's not easy but with a bit of support you will get better. Good luck Op.
