How Bad is It Going To Be

I ship in 10 days first of all. I know that boot camp isn't very hard, just from what literally everyone says. I'm good with push-ups and with sit-ups. But running. I cannot pass the 1.5 miles. I'm a god awful runner. I'd like to say I've been working on it the whole time I've been in DEP, and I have, but not nearly as much as I should have been and now I'm freaking out. Am I going to die? Am I going to pass? Running is the only thing I'm worried about. I know my general orders, my Creed, I'm learning rank and recognition, most of which I have down already.
