Please help me move out underage

Hi, im a 17 year old girl and I don't have a job yet to move out in London and I need to move out very soon I have had severe memory loss from narcissistic and reactive abuse 2 years ago and im regaining it. i have toxic household who manipulate me and gaslight me and I feel suffocated. I tried to end my life 3 years ago and was in the hospital and they still haven't learnt from their behaviour and keep denying everything. I hate being the scapegoat of this family. I have mind fog right now but I’ll come back to explain in more detail
