Scared of university

Hey everyone. I'm currently at a community college in my home town. This is my last semester there and am going to a university come January. Looking for some advise. I'm so intimidated by going to a university. I've been at my community college for about 4 years because well... life! And Im really comfortable there. Everyone keeps telling me that a university is so much different than a community college, work load is so much harder and double of it. Is this true?
