Getting back into your 'zone' is always so hard after a break.
It's really amazing, it's a little scary at first being on your own (on top of that I'm 4 hours away from home) but after the first week or so everything just feels right. You can do whatever you want really, you don't have to go to class if you don't feel like it (although I strongly do not recommend that, after all your paying for those classes might as well show up). Do you know what you want to do yet??
