Currently in NFAS, finishing up ET school with comp on April 1st. Suicide prevention is a huge deal here on both sides of the house (A School and P School). In fact, they have one chaplain for each school who sits in his office during school hours with the door open, and his only ongoing mission is to help students deal with personal issues. They also did away with anything greater than 25-4's (25 hours a week, 4 hours the day before a school day) on the A School side for the sole purpose of suicide prevention. So the only real reason that someone would try to off themselves here is because they don't have the stones to take care of their issues. The resources are here. Financial, medical, emotional, whatever issues you've got. All you have to do while you're here is do your job and make sure to vent the stress on the weekends (responsibly), and everything else is taken care of.
Academically, if you put in an honest effort, you'll get a 2.5 or better to pass. I didn't put enough effort into college (worked myself too hard in other areas of my life), and I have a 2.06 from my university after 3 semesters of hard sciences. Here, I have a 3.52, and I'm almost done with A School. I've worked my a$$ off to maintain that grade and do my job in general, but I've still got time to go on the internet, hang out with friends, go on a dinner cruise with my wife, etc.
On an entirely different note, boot camp in July is pretty much the best time to go. I was there from July 23 to September 14, and it was beach weather the entire time (aside from the occasional thunderstorm). Definitely beats sub zero and snow watches.
I wish you good luck in your future endeavors, whether the Navy is a part of them or not.
