Staying in Med School because of Sunk Cost?

Hi :-)
I've started my first year in med school and am having a very hard time adjusting. In brief, I'm concerned that I'm staying because I got a scholarship for the first year.

First off, I have PTSD from many things that happened to me as a child and young adult and have only recently (2 years ago) been able to escape the damaging environment I was in and seek professional help. I have bad anxiety. This is important context to my situation now.

Some of the reasons for me wanting to leave are : I had the idea that being a doctor would be great for me, but I have come to know the more mundane and disappointing parts of the jobs (mountains of paperwork, not getting much time with patients, the stress). I have a long distance relatiopnship with a man whom I love an incredible amount and I'm afraid I will be wasting time here without him or he will leave me because I am always stressed. My current living situation is stressful, I have to worry about my relatives and their issues too. I am frequently worrying over my studying, that I am not learning fast enough, that I will fail. I feel a pressure from those around me to become “successful” and feel like I would be a disappointment. I worry about finances a lot. I graduated with a biochem degree and I don’t know what other options I have. I'm worried I wont get a lot of time to do the things I love or spend quality time with those I care about.

Maybe most importantly, I won a full tuition scholarship for my first year of medical school. I knew it would be tough and I tried to commit to this one year because it is free. This is really why I feel I am staying. Am I committing the sunk cost fallacy?

Here is the important distinction between fallacious reasoning and taking advantage of an opportunity: If you by taking advantage of the opportunity you end up losing more than you gain due to the obligation you feel you have, then falls under this fallacy. For many opportunities, there is also opportunity cost. This is what it will actually cost you IF you take advantage of the opportunity. The question you need to ask yourself is what would you be doing if you weren't in med school? Which option is best for your life goals? (questions to think about, you don't need to answer them here).

Wow! First of all, congratulations to you! :) Secondly, I know this may sound like something a mom would say (sorry), but I don't think you would have won a full ride for the first year if you appeared to be unable to handle the workload - i.e., to learn fast enough. And thirdly, I agree with Dr. Bennett, especially since it's only your first year. Every choice we make in life costs us something, whether we realize it or not, and it's not always easy to count the cost, but if you try, the vision you develop for your future may help to see you through current difficulties . Wishing you all the best!
P.S. Consider pharmacy science?
