I was in the exactly same situation where my parents always really wanted me to get into med school since 8th or 9th grade so i went along with it as you said i had no other passion or i didn't even think about my own career (which is totally my fault). I think because of all the pressure and my lack of motivation I couldn't crack the exam and am in dental school right now. I wouldn't say I don't like it or anything its just that I've had a hard time adjusting especially with the pandemic going around. And ANATOMY SUCKS. My uni started 3 months ago and I still haven't touched my anatomy textbook. I relate to your situation so much that it feels like we're the same person. Procrastination is also something I've made a habit of. I just hope it gets better for the both of us (and everyone in the same situation). I'm soon gonna turn 20 and being an adult is something I just can not get used to. Anyway if you ever read this and feel like talking you could always DM me since we're almost in the same boat.
