Assalamu alaikum - I'm torn about my parents, what should I do?

Assalamu alaikum, dear brothers and sisters. I'm nearly eighteen and I've been quietly struggling for years. My parents often hurt me emotionally and I'm so exhausted. They punish me over tiny things (once I said "never mind" when my dad ignored me and my mum called me a very cruel name), hardly ever let me leave the house except for school, and they discourage friendships, saying I "don't need anybody." Recently I asked to go on a school trip for a few hours and my mum said I'm being "influenced" and that parents who let their teenagers out without an adult are foolish. She called me a disappointment and threatened to move me to a different school. They also say things that destroy my self‑esteem like "Make sure nobody knows your father's name, he'll be ashamed because of you," or "You're the reason I take more pills and get sicker," or "You say you'll take care of us when we're older but you can't show respect now." I love them. I don't want to speak ill of them. But I'm in a very bad mental place, have fallen into unhealthy habits, struggle to form real friendships, and for a while I've even thought I would never want children because of how they've treated me. I don't have anyone to talk to here - please don't suggest that - they're the only family I have locally, and school counsellors would tell my parents what I said. I'm in the UK doing A‑Levels and I'm unsure whether to move out for university (with the risk of heavy student debt) or follow my passion and do an apprenticeship that could be equivalent to a master's, which would probably mean living with my parents longer. I want to pursue my dream, but being at home is harming me, and realistically I might only be able to leave when I get married, which feels far away. There is much more, but this is already long. I'm asking for advice from fellow Muslims who understand our responsibilities to parents but also the need to protect our iman and mental health. What should I do? JazākAllāhu khayran.
