Courses and actual army life are 2 different things. Courses are made to be stressful, you are there to learn, get dirty, work as a team and then when the course is over life changes.
I hatred my time on Leadership course back in 1992, wanted to go home and do the walk of shame that I was sent and volunteered to come home and admit I failed. I asked one of the instructors and he said no. I finished the course and look back it almost 31 years later and realize it was one of the best things I ever started and completed.
Course life is not the same as life in a regiment or unit or HQ. You get time off, you get some space of your own if you live in barracks. Yes you have to keep your personal space tidy and neat. You do not have the instructors or staff checking in on you at all hours of day and night. You can wear your own clothes on after duty hours.
Every trade has those days of oh crap I have to go to the field and do what ever under tentage or in a hole. Or you go to sea for a tour, or whatever.
Some of the people here have been in your exact spot and finished it and found out it was not as bad as course life made it out to be.
Others have opted for a change of career and found out it took a long time, and what ever holding unit you are put in, they always had something for you to do.
Other people here will explain how to do the VOT thing and your free to try for it.
But before you do it, why not ask your instructor about life outside of the course, and what he or she really did at the rank of Pte in the regiment on a regular day, and get some first hand knowledge before you pack it in
