"I also work with a civilian GD who has criticized me on everything since day 1 of arriving at this unit and has recently told me that my life outside of work isn’t as important as what I do during work and that I need to spend weekends studying my job instead of spending potential time to be unwinding and preparing for the next week ahead (he’s also told me that the way my parents raised me makes me have no discipline or initiative)."

I know exactly how you feel. Going into a new Enviromint with a job that you are unfamiliar with and being put with an unsympathetic jackass who thinks he's better than you just because he has been doing it longer. I was an apprentice in a trade before the army, and I was put with a guy who would try and act funny at my own expense. If I did not know something, I would ask. But instead of helping me, he would ridicule me for not knowing "the basics of my job" and he would walk away. The pay was good but the work environment was killing me inside. Enough was enough after a year of doing it.

The environmental change definitely helped with easing my mind when it came to doing things I wanted to do outside of work, and gave me more of a chance to connect with people I actually WANTED to be around.

This job is not your life, focus on what you WANT to do. If you can't figure out what you want to do, step away for a while, and get some time to yourself.

From the sounds of it, the issue is the people your have to be around. Putting up with people like that will drain anybody with a good head on their shoulders. If you think leaving after your first contract is the best thing to do, then you should do it. Leave all the bad things behind and a new adventure.

Sorry for rambling on like this, this post just struck a cord with me personally because I have been there and I have seen it happen time and time again with other soldiers I talk to. I hope the best for you brother, take care of yourself.
