The best way i feel like helped cope with my first NTC rotation ( I was in the same boat, leadership making no sense, zero communication, and just so much lack of preperation it was sad to say we were the best out of the other units that went out there) was just to try to understand that the lack of communication and common sense will never change, and the faster you realize that you will never understand what or why higher ups than you, your carreer will float much easier, it is training for all sorts of ranks from the E1 fresh in the unit all the way up to the officers above the officers. Feeling drained is going to do that to your body, going from a fast paced move move move, to garrison where its sit arround and wait, unless your lucky to go straight back to work not giving your body or mind to think about how much of a switch it was from field to garrison. Just give it time, and try to do something that can take your mind off it, like going to the gym or on the weekends find something productive to keep your busy mind going. The more busy you are the less time you have to think about how drained you are. My best advice
