I couldn’t believe your question, and I have experienced the same things all my life! While growing up, my dad and mother told me, you will not and can not amount to anything worthwhile. They would say things like this when they were mad that I couldn’t understand at the moment about math issues in particular. When I hit sophomore year, I was excelling and as soon as I became the best, I stood down and let others around me down. I had to something deep inside me would trigger and make my physically sick, when I dropped it I was ok.
Still up until the present my subconscious mind still runs my life, after being severely beaten when I was a corrections officer for the state. I was nearly killed it retired me ten years ago! I have a double decker slap down, starting from my upbringing up to my near death experiences! I know what you are feeling right now and I wouldn’t wish this on my worse enemies. I have a bad case of PTSD. Been dealing with it for the past ten years.
My opinion, these will work for you with a sensible approach, you can’t mentally control your outcomes! But there is everything you can do to listen and by keeping hopeful, which is why I am here today! My goal is the spiritual because this is where my essence is! I am meeting it where this path will eventually take me. Thanks for being out spoken, I thought I was the only one who felt the sheer power of subconscious bad programming.
