19 m feel like i'am running out of time

I'am currently in my second year of dentistry school. In a private uni so everything costs shitload of money even failing a subject. The thing is that I don't study . I feel like I don't want to do anything with my life . I feel that even if I graduate I still won't be happy because it was never something that I liked I just started it for my mom. Even if I became famous I won't be happy . Even I had alot more money I still won't. I never been in a relationship in my life even though I had ton of compliments about my looks . And above all that I think I hate looking at my body in the mirror having gyno makes me feel like shit even tho it costs about 300 usd to do it in Egypt. I don't have a goal or a dream I feel like i'am just existing but the uni stress is making me feel even bad because I don't like it and I don't ever feel like studying. I wanted to be a prosecutor but my mom thought I wouldn't study hard enough in law school so she fucked me up in a private uni. My question is how to convince her to let me drop so I can travel to any country were no one knows me so I can buy a small studio and work a minimum wage job and my mind my own business. Sorry if I forgot any comma's or dots and pls don't mind my mistakes
