focus on getting your bachelors, continue that for sure.
If 4-5k per month is in dollars I would look in to hiring a part time person to help out with bug reports/support tickets to free up some of your time. Finding someone good might be tough, but look first in your circle of friends. I expect a fellow student would be looking for some extra spending money. Test out a few of your friends for the position.
Other than that it sounds like you've built a great tool that's making good revenue.
http://startupsfortherestofus.com has some great information that can help you I would start listening to those especially the ones relating to the problems you're going through right now.
Last thought is maybe relaxing some, setup an autoresponder to bug reports and tickets that you have received their bug/request and allow yourself some time on the non-critical ones.
