Oh I'm so sorry, Iwant, that you was/is on the receiving end for gas lighting. This erode your sanity and "makes you" crazy even if you are not crazy. Don't laugh but I was convinced at the time when I kicked out my xh that I was the crazy one. When I got back to work my boss sent me to a psychiatrist who explained to me that I was sane. I was having a normal respond to an abnormal situation. The first thing I did after that first meeting was to call my oldest son. His response; But Mum did you really think you are the crazy one! I can laugh about it now, 3,5 years after but in that moment I wanted that psychiatrist to put it on paper so that I could put it on my fridge to look at. I'm not crazy I'm not crazy!
The gas lighting is severe since the victim is often isolated from outside input (aka reality or normal) so the victim is starting to believe the abusers reality, or the abuser wants the victim to only have the abusers reality. It is crucial to not isolate yourself, have someone who can be your "normal or reality". Heck I didn't know if up was down or the shy was pink but even if I was made totally crazy there was some grain of sanity in my head. Things he said didn't happen (that I know happened). I went to the place in our house where it did happen and I could feel it happened I know it happened right there. (like you do when you forgot what you was suppose to get or do but forgot what it was, you go back to where you thought about it in the first place
Without knowing it then, but I know now, in hindsight, I did "use" a lot of people in the beginning to kind of validate what is normal and what is not normal behavior. Best thing for me and my recovery. I think for me it's very important for you to look inside yourself, what are your core values, morals, ethics etc. the faster you can ground yourself the better. I hope you understand what I mean.
