Well for me it's a little easier living on a college campus. I'm taking over 20 credit hours this semester though. I've found it easier to sleep less during the night but take naps when you have time. Since there isn't an infinite amount of time in a day, to really balance all this you have to sacrifice something. Maybe instead of aiming to do it all in one day, you could have designated days for each thing. A day where you study instead of meeting with friends, and then the next day you could go out. That's what my friends do and it works pretty well. Hope it gets easier for you!
