I am not a child psychologist, It seems to me that you suffers from complex ptsd because of trauma you experienced as a child.
Did you ever confront your mother as to why on earth she agreed to the dentist taking out all your teeth at 11 years old? Did she even seek a second dentist opinion? It seems a cruel thing to do to a child.
I went to a primary school with a dental practice attached to the school, up to 11 years old I have fillings done but never have any teeth extractions. Can you even grow a new set of teeth at 11 years old?
If you suffers from essential tremor, how about meeting other people at a cafe and not buy any drink just food.
I grew up with a schizophrenic mother, she lost her first 4 children and it pushed her over the edge, there was no abuse just chaos.
My husband, on the other hand, is a son of an alcoholic and a scapegoat in his family. He tried to take his own life in his forties, this happened before I met him and on hindsight, could benefit from some kind of therapy.
