I would take a bit and consider if your feelings are changing because you are tired with your current situation, particularly with how odd of a college year this has been with the COVID considerations, or as you've been learning more about your future profession, you don't see yourself being happy being in the Army following graduation. If you don't see the Army as a viable career for at least the few years you'll be committed to after graduation, there's no shame in finding a different career path, but make sure that's what your decision is based on.
I will also add that ROTC is a very different life than the Army, and if there are concerns about whether or not you'll be able to do the jobs you see senior cadets doing, everyone goes through the same learning pains. There are very few, if any, people who are born natural leaders; for some its definitely easier based on personality or previous experiences with teams and what not, but most folks, if given the opportunity, can take the time to develop and grow into their own leadership style that can make them an effective leader. That's why they have you work on your leadership skills in progressive sets of responsibility through ROTC before sending you out to the force, and even then, as a junior officer, regardless of your field, you're going to be put in situations designed to continue your growth.
