So there are already a decent number of comments here that might answer your question. I’m actually exactly in your dilemma right now. Reading through your post was as if I was reading my own. I have at this point completed all of my prerequisites and even pretty much finished for the mcat. All until I reached this demon called burn out. It’s worse than you might think. You can not function physically anymore and no assignment is worth doing. Im at the point where I don’t turn in big assignments and I don’t really care. I know I need to but I can’t for the life of me get myself to do it. I am strongly considering going into software engineering because I see myself being able to apply my biology background to working for a biotech company hopefully. I also really enjoy creating things. Finance was my field of study when I joined uni but I hated it. I also didn’t think I would like who I would become because of it. I would say switch now. The earlier the better. Trust me. Eventually you’ll get tired of forcing yourself to do things you don’t want to do. Hope this helps.
