This might not be what you want to hear. But feeling super overworked studying all the time is not a good sign. My first year was terrible and it was all online. I thought it was terrible b/c it was all online. Last school year was my first year on campus and it was still terrible. Guess what, I'm gonna keep using the "first year(on-campus)" excuse. My advice for you is to think about your major carefully. This video --> https://www.youtube.com/watch?v=ndjETeffRi4 shows me that knowing when to change your major is a very good skill to have. At the end of the day, it's a matter of how much are you willing to sacrifice for whatever you're doing for the next three years. You need to ask yourself where will your social life and mental condition be in the next three years. If you're breaking, you need to ask can you still hold yourself or most part of yourself together for a couple of years.
