At the age of seventeen in order to attend university, or at least I was there most of the time anyway. During holidays, however, I had no option than to live with my parents.
It was when I found a job, almost right away after graduating, that I was able to move out permanently. My mother tried to find all the ways she possibly could to prevent me getting out, but I was highly assertive at resisting these because I simply wasn't able to handle living with my parents.
Yet I had been told that if I was to leave school and not go to university, I was getting shown the door at 16. In retrospect I would have been vulnerable out there in the world on my own, yet due to an emotionally abusive father in particular I would have been quite happy with that option.
