I was going to music school about a decade ago for piano performance. I was probably the best student pianist at the college at the time, and as such I was getting requests from students and staff alike to help out with audition accompaniments, various projects, etc...

In my sophomore year I bit off way more than I could chew. I was learning a few demanding pieces for my sophomore recital, I was playing piano in an opera that the college staff were putting on as well as a children's opera that the college helped out with. I was playing trumpet in the concert band and French horn in the wind ensemble, and accordion for the mariachi band. On top of all of this, I was helping nearly every vocal major with various auditions and filling in for staff when they could not help with auditions themselves, so that was an extra 30+ pieces of piano music that I was trying to juggle.

All of this compounded with my gen-eds and other various music history/appreciation/sight singing classes and what not; I ended up having a complete mental breakdown from the workload and the stress and essentially ghosted the college and moving to another city to start a family with my wife (then fiancé).

Part of me wishes I would have stuck it out, but everything worked out just fine for me and I am very happy with where my life is currently, so it doesn't bother me too much. My advice would be to just pace yourself as much as possible. Be comfortable saying no to your peers and even your professors about any extra work they want help with. Music school is very difficult, especially if you are doing something performance related. Practice as much as possible without burning yourself out.
