I think you should really consider talking to a mental health personel on the base, or if you're worried about the confidentiality you could talk to one of the chaplains, both would definitely be able to help you access the help you need. The military is becoming a lot more open and understanding of the mental health issues of troops. I encourage you to continue to try and get another position. I know it's hard and a lot of hoops to jump through and it doesn't seem worth it a lot of the time, but it will pay off. Use this time off to find help, you mmay even consider making an appointment with legal to discuss your options.
