A friend completely wiped out all of my google drive? what do i do?

That sucks. Do you remember anything from your presentation or paper? Try to finish it up and don't leave your google account open..is your presentation and paper long?

I think right now you should contact your teacher and let them know you are doing everything about it. Also try contacting tech services. If you still have the files you might be able to use the go back option and get everything back.

As p said, you have a chance contacting their support. As a support tech myself, I can tell you that there's a good chance thy have backup systems and can retrieve your data. But, you should contact them as soon as you can. The more time passes, the chances go down

Give that "friend" a good kick

They are gone for good. NEVER keep only one copy of any critical files. And why did you let someone else access your files?

you're screwed. and that person isn't your friend. you may be able to contact google customer support and they may be able to restore your information as it is likely still stored on their servers somewhere. but that is a long shot.
