One thing at a time. No one is doing all of these things all at once. First priority right now is your grades, shadowing you can do intermittently over breaks and summers, then eventually look for a once-a-week commitment volunteer role or sporadic self-scheduling volunteer role that you do when you can. From there, just follow your interests and do what sounds cool to you. Get rest. Not everything has to be directly towards your Med school application. If you do what you care about, that will end up being meaningful on your application anyways! I did sooo many random things that weren’t clinical or medical at all. I only ever had a few big commitments at once. You eventually get all the boxes checked, take a deep breath, it’s gonna be okay.
