At 17, the physically challenges were daunting but not overwhelming. At 17, the emotional and social challenges were so overwhelming I used one of the few recourses available: Chaplain's Mast. My DI was not happy and the CO offered to transfer me into the Navy where I could train as a corpsman (Marine Corps version of a medic). One of my greatest regrets is not accepting their offer but it would have required extending my enlistment. I adapted. Near the end of boot camp, my favorite (if there is such a thing) drill instructor said he was not only amazed I didn't washout, but that I had somehow managed to become a 'darn tight turd.' High praise indeed.
