Sometime in my middle school years ~ I had the misfortune of being bullied on a daily basis so my mind and body took on a defensive/predatorial survival mode and all other things got pushed to the side until I had some alone time or peaceful time to let my guard down; I'd say maybe age 12 or 13, I realized that everything just felt wrong, and i was severely depressed but no one could figure out why ~ I went to 3 different psychologists who hypnotized me, dosed me up, diagnosed me. I took anti-depressants for a while but it didn't help (it helped to some degree but the depression always came back). No matter what i did, the depression remained, so I knew something was "off" around my middle school years, and it wasnt until around September 2012 that I started making a closer connection (once I was already an adult living on my own, with no friends or people I felt I needed to "impress" or "hide from", so I was officially no longer in survival mode because I had no one to fear... other than my wife lol)
So while I made the true discovery not too long ago, my life never made sense as far back as i can recall the confusion setting in, which was about 6th or 7th grade ( 12-13)
