Congratulations! And yes, what the first commenter said, relax, go on a little vacation, and spend time with family and friends. Also I would sit down at some point with your family and whatever close friends you spend the most free time with, and explain to them that you are about to embark on a journey that is very time consuming (meaning that it will take up the majority of your time, most of the time), and probably one of the toughest journeys that you'll go on. Well worth it, but tough and time consuming nonetheless. I say do this so that when things do start to get hectic and busy and stressful (and it will), and you aren't able to meet up for a party, or a birthday, or a holiday, or something like that because you have studying to do or school work to get done, they'll know why. They may not always understand, but they'll know why. I always heard people say before I started my program that "You won't understand unless you've gone through it", and it is 100% the truth! Hahaha. You'll spend a good portion of your time with your classmates and I find so much now a days that there are just some things (feelings, emotions, stresses) that you'll feel only your classmates going through this crazy journey with you will/would understand. And that's ok. So, relax, sleep in when you can, spend stress-less time with your family and friends, go on a vacation somewhere, even if somewhere small and/or local, read a non-text book (if you like to read), watch some movies, and get some sleep. I know I said that twice. Hahaha. Much luck with all your studies, and again congratulations!
