How to deal with a Long Distance Relationship?

I have been dating this girl for 6 months but she just moved to Chicago (I'm in Texas) for college. Her school is year round so the only holidays she will get are Thanksgiving and Christmas, however I don't think I could go that long without seeing her.

I've tried distracting myself with friends and doing my hobbies but I always get this knot in my throat and tear up a bit randomly. I really never cry but this feeling is just different and it's hard to explain because I've never experienced it before.

If you guys have any ideas, please let me know because even though we are still together, being away from her broke my heart.
