I would move into an apartment closer to school, do some vanity stuff I want to do but don't want to waste money on like some new clothes or spending $500 on a good dentist/dermatologist etc. I don't think I would change any of my other spending habits. Maybe I'd splurge on a new pc or something.
Other than that I would keep it all in the bank till I come across a good investment opportunity or till I want to invest in a business of my own. The biggest difference would be that I wouldn't have any financial stress or stress of depending on others for the foreseeable future, which would be awesome.
