How old are you? Are you in college or high school? Are you a recently graduated HS student who transferred to college with junior standing? Or are you a traditional college junior?
It would help to understand your situation a bit better.
Believe it or not, there are jobs that medical anthropology majors can get if they don’t get into medical school. Most will require some additional education or training. (But the same is true for biology or chemistry majors who don’t make it into medical school.)
See [MEDICAL ANTHROPOLOGY @Northwestern University](Medical Anthropology: Department of Anthropology - Northwestern University) for a list of potential careers.
Are you at all interested in forensic science/anthropology?

You can also make an appointment with the career counseling center at your college to get some other ideas. Or try striking up a conversation with your fellow medical anthropology classmates and ask them what their career plans are.
Two sciences/quarter is doable, but it will require very good self discipline and time management. Medical school requires a great deal of chemistry/biochemistry so it’s important for you to do well and get a firm foundation in chemistry. Not doing well in your chemistry classes is a sign that medicine isn’t good fit for you and you should think about looking into other careers.
And since med school is all science all the time. (Equivalent to about 5-6 science classes/semester or 4-5 science classes/quarter), if you can’t manage to be successful w/ 2 science classes/quarter, maybe medical school isn’t the right path for you.
I cannot believe that the academic support center at your college only offers tutoring at night. One of my daughters was a chem/physics/math tutor at her undergrad’s tutoring center. She worked several afternoons each week. So did most of her fellow tutors. Check w/ your college’s academic tutoring center. You may need to schedule them farther in advance than night sessions, but I can almost guarantee daytime appointments are available.
I would also suggest given your level of anxiety that you make an appointment with student health to get some counseling. Talking with a trained counselor can help you develop ways to control your anxiety and to find healthful outlets for your stress & anxiety. They may even suggest some ways to connect with your peers on campus. Medicine is a social profession. You need to be able to interact comfortably with a wide range of people under intense situations and in very difficult circumstances. To do that you don’t need to an extrovert, but you do need to have excellent people skills.
If you are so shy, you can’t talk to complete (and sometimes angry & hostile) strangers, then medicine isn’t a good career fit for you. Talking with a counselor can help you decide whether to continue your pursuit of medical career or not.
RE: commuting. Is there any way you could convince your parents to allow you to dorm at college? Even just for a year, until you’ve gotten through your hardest classes? Are there financial considerations that prevent you from living on campus? Cultural issues about living away from home?
