@Burning_black_roses well think about is, is medicine something you love to do? Do you wanna do this for your life? Sometimes people are difficult, they see only what they wanna see, but it's up to you to prove them wrong, you already work hard, even doing the tasks most people don't wanna do. That's something that takes balls, even if you hate it your still doing it.
I also plan to study medicine, hut plans change because money is a huge obstacle. People have different expectations, they expect you, at least your elder expect you to do better or to do as well as they did, because most of the time they wanna see you succeed.
As for you assignments, space them out, work them through and take your time, you need to have rest as well otherwise your kind won't function, do the assignments one by one, in a steady pace, don't rush or Tey to do it fast to fit the academic pressure society's expectations. Everything you do you need to do it at your pace not anyone elses
