I really feel like I'm going crazy, please help me...

I've earned all the money to get plastic surgery, but I can't because my parents never let me. Honestly, I'm a 24-year-old adult. I'm not asking for money to get plastic surgery, but does it make sense that I can't do it because they didn't ask for permission? What kind of child am I..? If I'm planning on having plastic surgery someday, I think the sooner the better, but why are they preventing me from doing it? How does everyone get plastic surgery? I thought all I needed was money, but due to my parents' nature, I couldn't do it secretly and I had to live like this. My life was so pitiful that I thought I would go mental. My parents are so seriously conservative (everyone hears me talk and is surprised that I feel like I'm living in the Joseon Dynasty). ) I feel like I want to die. Really, I want to become pretty too... I'm living this stressful life looking at the sex artist every day... Will my parents be sorry if I die? It's so frustrating that I feel like I'm going crazy. Living like this makes me feel like I just want to die.
