you really have to love medicine and be motivated to become a doctor. honestly i’d imagine undergrad is probably the easiest part. have you worked in a hospital or shadowed any doctors? you might find it’s not actually something you want to do.

if it’s really what you want to do, then it’s possible, it’ll just be extremely difficult. you’ll have to start at a community college most likely and go from there. good grades alone aren’t enough to get you into med school.

unless you want to end up where you are now, you’ll have to figure out why you’re failing and change it
