It's not that bad, John. You've probably withstood much worse. Training in the military is all a mind game, and when you complete that game, you're "one of them". Suddenly everyone who was a complete and total dickhead to you in training is suddenly praising you and giving you respect that you EARNED. It was the first time in my life that I truly felt like I had accomplished something all on my own.
It's more than a simple pat on the back for a job well done; you entered into a fraternity of millions of people before you and millions more to come after you. That feeling never goes away, and I miss it to this day. I decided to get out because my life was going in a different direction, but that doesn't mean I didn't love every day of being in the military. Sure, some days I hated the unit I was in, but the military was probably the single best thing that has ever happened to me. It turned me into a man, made me more responsible, made me a little more selfless, and much more disciplined even to this day. Fuck I miss it.
I would highly encourage anyone of any background to join the armed forces if they want structure, discipline, and pride in their lives. The problems that arise are only when people abuse the system or take advantage of their position...but that's what the Inspector General is for.
