Welcome to M3!
The whole year can be rather arbitrary, and it's best to just accept that's how it will be.
It gets much better. You have to start somewhere low on the totem pole. The first step in an apprenticeship is usually observation. We did that a bit as pre-meds, but without much of a foundation/knowledge background. Now you have the basic medical education to get something out of observing an experienced physician. Ideally they give you some slack on the leash and let you interview patients on your own/present/etc, but unfortunately this varies wildly from school to school and even rotation to rotation. I worked with some students on my away rotations who essentially spent all of their M3 shadowing (more common with DO students who rotated through only community hospitals).
M3 is a long year of complaining about the arbitrariness of grading, of how people get assigned to rotations, about how unimportant we appear to be as medical students, how miserable hours are/how little control you have over them (and your life in general).
M3 gets a lot better when you accept that there are some things you can't change about it. Take it a day at a time and go with the flow. Work within the system you have, because frankly you won't change it in time to benefit you (but do give feedback to help future students).
If your attendings aren't teaching you much, then learn even more on your own.
It will get better.
