Advice on inheritance , 21 yo senior

In a unique and awful position where the passing of my father has left myself a large sum of money in the amount of $2.5 million dollars or so. I’m looking for general advice: should i get an advisor, should I invest myself, do I never touch it (i’m a student planning on attending medical school within the next 2 years). Additionally, there is a sense of privacy i Want to maintain with something like this, how does one go about that?
