Girlfriend has gone to uni - need advice

Me and my girlfriend have been going out nearly a year. Met in college and were head over heels for one another. Basically seen each other every day for nearly a year. We have an argument every now and then each month and when she's in that mood she says how she thinks we won't last in uni and how I'm boring (she apologies an hour later and says how she thinks we will and how she loves me). She then jokes around sometimes and says how she's going on the pull. I have mollicoddled her a lot really.
She's never been clubbing and is going clubbing real soon, she's doesn't really drink either. Even though I know she won't flirt with anybody, I just keep having thoughts and images in my head that she'll meet someone new and leave me, like I'm imagingig lads coming up to her and trying to flirt with her when she's at the on campus bar or when she eventually goes clubbing. Them thoughts are making me dead nauseous as if I could be sick. I miss her and she says that she misses me too. She's not really the big affectionate type either might I add.
I don't want to lose her, honest without her I'd be in a bad state. The fact she's moved away all be it she's only an hours bus drive away has killed me. Obviously because she's socialising with all her flat mates and hall mate she she's not speaking to me as much as usual. She's been to the on campus bar 2 nights and I've spoken to her here and there when she's been there. I'm jealous of all these new people she's meeting because they are with her. I know it will be hard the whole uni thing but I want to try and do my best with it. I know I'm clingy and need to stop that as much if I want it to work.
We've facetimed and called each other numerous times everyday she's been away.
Even when she is staying out at the on campus bar and coming back at 1am and We're not facetiming till about 1:30am till about 2:30am. When we're face timing late on as well she can be dead sweet and cute towards me.
Before she left for uni me and her spent basically over 2 weeks staying together and she's said to me a couple of weeks back "no matter what don't let me lose you" and on the day she went uni she said "this doesn't change anything for us you know, me coming here"

Just want some advice or some opinions on what I've said. If anybody is in a similar situation or have been, or if you just have an opinion or advice on me. Anything will help
