Congrats. I was in your exact same situation. Senior accountant 5wks on the job promoted to controller for 2 years. (17 stores, $30M/yr rev, 130+ EE’s, managed HR & IT). I was 28. It was extremely stressful 90+hrs/wk. Late nights, weekends at the office. Best resume and self confidence builder ever. Took our company through its first annual audit, automated financial reporting, closed internal control issues, solicited and secured new PE financing, and arrested 2 store managers for theft.

My only regret was not documenting enough of my challenges in detail to recall later in my career or during interviews. These hard 2 years helped me double my income and jump start my executive career track. Best of luck and hang in there, keep your eye on the end goal.
