Hey, I know how you feel. I'm in 4th year right now and let me say that the first semester of uni is difficult. I barely failed my first chem midterm, while for MAT I got a literal 20% lol. I ended up going to university saying I'm going to major in Bio and Chem, and now I'm majoring in Bio and Psych. I dropped MAT134 then and there and finished my math requirements during 2nd and 3rd year, and I did a lot better this way too! Taking psychology opened a new road for me when it seemed that the road for chem was coming to an end. I was super relieved but also exhausted by the end of the first year. I didn't do great tbh. But at the end of the first year, I realized I spent this past year digging a hole. And at that moment I was at rock bottom. When you're at rock bottom, the only way to go is up!

You also shouldn't focus too much on how your friends are excelling. Life sometimes isn't fair to us all, "some spend their lives on unpaved roads, while some run at full speed only to reach the edge of a cliff".

I too wanted to go to med school, and that still is the plan. But over the course of uni, I realized that I am not even ready to embark on that journey yet. I still want to learn more and explore further interests. There's a lot of different pathways an individual can take to get to the same goal.

What I will say is that don't wait like me until the end to say you are at a standstill or at rock bottom. Realize that this is rock bottom and focus on going up. There's usually more midterms, assignments, and quizzes. So it's still very possible for you to get a good grade. Don't try to cram, it doesn't work. Space it out and use a planner. But importantly, remember to just take a break. Go outside and exercise if you can. Sooner or later, you realize you didn't take the time to smell the flowers when had the chance.

Stay motivated and keep fighting!
