Hey there Ash I,
I'm probably not the best person to help you feel better about your situation, or any situations at all. But, I think I am basically in the same shoes as you are in right now. I've had a disastrous freshmen year bombing many pre-req science classes. That year was a whole shock for me as I came from a reputable high school as a 4.0 student dropping to <3.0 in my freshmen year. Just yesterday I was re-analyzing my last year's performance and realized that there actually is a high probability that I had depression. I even thought of taking a year off to get myself together but I already made a commitment to the school as one of the student leaders for my sophomore year so I just couldn't do it. I thought long and hard if I even had a chance at any MD schools since it would take a very long time to raise by cGPA to sub par level.
Here comes the sophomore year and I took many science courses again. Overall, much better performance, tried to be mentally and physically healthy, and being pre-occupied with school activities have kept me busy and also helped me with time management. Except for one science course in my second term, my pre-reqs ranged from good to excellent. I'd say one another thing that helped me with this improvement was trying to figure out what I was really interested in learning about in science. I catered my courses to those areas of science and that helped a lot.
Unfortunately, my good streak didn't last long enough as I've been taking a full year ochem at another institution during this summer break. Chemistry has never been my forte since college and I was against all the factors to get a good mark. I know that this 8 unit credit will do some major damage to my cGPA now, and once again, I've been thinking if I even have any chance at any schools. My folks would probably kick me out of the house (jkz) but they would definitely be disappointed. I've been browsing through other careers like, nursing, dentistry, and PT but just like you, I couldn't imagine myself having one of these careers for the rest of my life.
I've failed myself and my parents so many times during the last two years, but I hope that for my last two years I could continue to demonstrate improvements and rock the MCAT. I think you should try to figure out which area of sciences you're most comfortable with and try to take as many upper year courses in that field. That should start to bring your confidence level back up and you'll be rollin' again. No one said that you need to have BSc to be a doc; you could get in with that business degree. Maybe you could take a few science classes with your business program and see how it goes...I know a couple of people who are doing that actually, and they're doing quite well. Have you considered being a DO? They would replace your bad grade if you retake it and do better. I am certainly aiming for DO now. Not just because of their holistic view on your applications but because of their philosophy as well.
In terms of depression...maybe talking to your family about your situation may alleviate the stress you're carrying on your shoulder. Keeping yourself always busy with various enjoyable activities, perhaps in clinical field, would give you that extra motivation that you just needed. Well, that's what I'm planning to do for my Junior year...
I hope this long post sorta helped you in some way. Just don't give up because of your first two years. Not everyone became a Doc following the traditional route 😉
