My grandfather gifted me a large sum of money. Don’t know what to do.

My grandfather recently gifted me around $150k for the new years. So i have about $190k just sitting in my bank account all of the sudden. I am 19 years old, full-time student, no consistent income, living with a roommate. I know nothing about finance and I'm honestly more conflicted than happy. What should I do with the money I was given
