<human>: Can you provide a brief rundown of the text in within 3 sentences?

My girlfriend is going to be leaving for college in about 1 weeks time. I am absolutely terrified because I've been with her for almost 4 years, and I love her more than I can fathom, and, from what I've heard and seen, LDR's are where some relationships go to die. And that utterly terrifies me.

There are times where I will be able to visit her how ever, with a possible job and some schooling of my own it might be hard to actually find time to see her. Am I just overreacting and over thinking? Is it a legitimate concern? I just need some advice to make this work.
<bot>: S.O and I are about to start a L.D.R and I am wholly unprepared and terrified about it. Some advice to help keep things going smoothly would really ease my mind.
