I am still in college and am on the pre-med track. I am ambiguous about whether I should go for a MD in primary care/internal medicine or just go for optometry school. What is holding me back from medical school is that I am unsure if I am physically and mentally strong enough to endure the many years of sleep deprivation during medical school and residency. Now, I am in a top 20 liberal arts college and sometimes feel that my course load is overwhelming and I stand in the top quarter of my class. I know that if I am determined, I would most likely get through medical school but it will cost a good extent of my mental and physical well being as I often get sick from colds during the school year (~3 times; my immune system is kind of weak) and I often experience anxiety (managebale level) and get tired more easily than my friends though I am athletic and enjoy playing many sports. I more interested in pursuing a MD because I am genuinely interested in learning about medicine and I like to practice a variety of medicine with a depth. I enjoy being valued when I consult patients and encourage them. Since I have an innate ability for bussiness, when I get my MD, I would like to have my own clinic, settle down and work from 9-5. If I were to have a DO degree, I would like to practice indepently and maybe own a glasses store. Questions Will optometrists still be desired in the next ten years or that all these big retail stores will drain the profession dry in the future? To what extent do you have to sacrifice your health during med school and during residency? i.e. How do your health compared? Any other constructive advice to jelp shed some light on my current situation would also be highly appreciated!
