<human>: Can you give me a shortened version of the text?

My girlfriend (17) and I (15 M) have been together for five months. We're really into each other, and we want to be together for a very long time. The thing is, she's graduating next June. She'll be going off to college and leaving me behind. She wants to stay together, as do I, but no one I've talked to about LD relationships has positive things to say. So, I'm asking Reddit. Do long distance relationships work? What are some ways to help make them work? Is it pointless? Will we be wasting my time by trying to make it work? Thanks in advance to any opinions! All will get upvotes!
