Mourning college as a student teacher

I know this is somewhat of a non-issue, but I miss being a college student. It's hard to see all my roomates and friends having fun in our last semester of college while I'm stuck to such a rigid schedule and have so many commitments/responsibilities. I thought I would get over it but i'm almost halfway through my placement and still mourning my old routine. It's scary knowing that once i'm finished we'll all be graduated. Student teaching is just so stressful and I don't even think I want to be a teacher. Just needed to rant and see if anyone feels the same and how they get over it.
