nray25, don't forget the chaplains - they are skilled in counseling in these types of situations, and it has nothing to do with their faith group. You don't have to be a regular service-goer; they are there for you. They will help you to think through how to approach your parents and understand their point of view.
Whatever else you choose to do, don't give up on the academics, because that's the portable item of value you can take with you, in terms of course transfers, to other schools, if that's the path you take.
Remember when you were "little," and all you wanted to do was be grown-up, out on your own, responsible for your own decisions? Well, now you are, and learning how to keep your head up and put one foot in front of the other as you journey through challenging portions of your life IS being a grown-up. It is definitely not fun at times. There is also great reward and confidence that comes from facing tough times and figuring out the way ahead.
If you come to know in your heart these are not transitory thoughts, then you have to focus on the long poles in the tent: (1) working on a plan to get your college education (2) speaking as a responsible young adult with your parents to collaborate on a plan (3) keeping your academics up and leaving on your own terms, not doing the self-destruct thing so you get asked to leave.
I left out any mention of gaining a commission through other means. Military life, while indeed not the same as at a SA, is a life unlike any other. Deciding whether or not you want to serve in uniform is a different, but inextricably related, decision than the path that takes you there. Military life is not all glory and waving flags, it can be life and death, as well as an everyday job filled with inanities (and occasionally idiotic peers and senior officers). The inanities seem to be getting to you there. Once you raise your right hand to take the oath as a commissioned officer, you cannot walk away if you don't like it. We could fill the forum with posts from former and retired officers/enlisted, spouses, recently graduated cadets and midshipmen, as well as currently serving officers and enlisted personnel, on "inanities, idiotic peers, etc." as well as the tangible and intangible rewards of service in uniform.
I'll be keeping you in my thoughts.
