Yeah, I'm sure you just eased his/her anxiety...

Until they have all the info they need you won't hear back from them. Plenty of cases in the past where people waited for months.

If it takes much longer I'd ask a sponsor to reach out to the HR and check up on you.
If you don't have a sponsor try to attend a job fair maybe and ask them in person.
As a last resort I'd make a phone call but not until a month or so from now.

Easy for me to say but try to focus on other things right now. Spend time with your friends and your family, in the long run that's what really matters anyways.
