Quasi-Quarter Life Crisis

To preface this, I am currently a 22 year-old, full-time college student, interning at a Big 4 accounting firm while concurrently taking 5 undergrad courses (all online) and 2 grad courses (all online). I am also studying for the CPA exam, as I have to take FAR on May 5th. I graduate in May with my BS in Accounting and am already pursuing my Masters which I should receive by May 2024. Additionally, I've already signed a full-time offer with the firm I currently intern for, now scheduled to work as an associate in Summer/Fall 2024.

With all of this in mind, I am honestly losing my shit right now. I cannot handle working during busy season while studying for the CPA and doing schoolwork, all at the same time. Sometimes, I genuinely regret even going into Big 4, let alone majoring in accounting all together, to the point that I cry. I would much rather work as a financial analyst or in an industry related to investing/markets as opposed to this shit. I feel like something has to give at some point: either I join Big 4 AFTER finishing the CPA exam and my Masters OR I just go into a different firm (maybe a smaller one) while doing both. My concern is that I won't be able to make good money or even land a good job (w/o the experience) if I don't do something safe.

If anyone has any advice or has experienced this same situation, feel free to express your thoughts. Thank you in advance for any help.
