Thanks for sharing this, I can definitely relate to the removal of responsibility in undermining my own self-efficacy.
The example of this that comes to my mind was my college process, where the questions my parents posed to me were not, "Do you want to go to college? Do you think college makes sense, based on your dreams and goals?" The question was, "Which college do you want to go to?" I ended up going without direction and with an underdeveloped self-concept. This made me susceptible to peer-pressure, conformity and participating in activities that were dangerous to my health. I was also disinterested in actual learning. I finally broke out of it, but I would definitely say I was lucky to survive unscathed.
A key resource in developing my own self-efficacy has been Nathaniel Branden's Six Pillars of Self-Esteem. It contains some really helpful sentence-stem exercises.
Are you familiar with the book?
Thanks again and sorry you had to bear such treatment. I am glad to see you're evolving past it though
