What does this dream mean?

Ok I havent ate havent slept in 3 days all together. when I did fall asleep it was less then an hour and this same dream keeps happening. The past few days I have been on a cruise with a great girl but me and her live many miles away from each other. Ever since the cruise ended in San Juan porto rico she has gon back to san juan I have gone back to canada. Ever since I have missed her like crazy I have her email face book number but i just want to see her face. My dream goes like he and me are on top of a familiar parkade and she keeps telling me to come with her and she keeps jumping off the parkade into traffic and I keep holding back but everytime I get closer to joining her, she tells me we will have a perfect life together. Every time she jumps I wake up yelling, i pretty much cry everyday my friends and teachers keep asking me whats up and I keep blacking out on them when they are only trying to help. I have been taking a deppresion pill and it someone helps but only for an hour. What Im asking is what do I do? I wanna just see her face to face again! What the hell do I gotta do to stop recieving these dreams please help me. Please dont say Im on crack or anything like that I need advice not critisism!
