My boyfriend and I were long distance while he was in law school (5 hours apart) and truthfully, it was terrible. I couldn't be there for him when he had a hard day, and working to find time to be together was a huge effort. From my standpoint, medical school will be even harder. If it's worth it, it's worth it, and we made it through okay - but now that we're facing the potential option of LDR *again* with me moving for school, after six years, we're in the same boat you are. Nobody wants to not be able to be there for their SO when they're going through what may be the hardest time of their lives, emotionally. :/ I wish I had an answer for you. It CAN work out, but only if you're both committed to making big sacrifices for each other, and even then it's still like a long, drawn-out heartbreak.
