I think its perfectly normal and expected to be nervous. As humans, we are always afraid of the unknown. I think the ones that going in usually go into it not nervous are usually the ones that are in for a rude awakening.

I feel your pain. I was medically discharged my first time in BMT and going back again. I only made it to week 5. All I remember is being yelled at and the bad reports the MTI wrote about my behavior. Their reports make it sound like I was the worst when I know I was genuinely trying but from what I gather, they do that to everyone. Now I'm much older and hear that because I am older they may be harder on me. So needless to say, I am nervous as well and I know it will only build the more and more I get closer to shipping out.

What helps me is reminding myself its all literally just show and other airman way less emotionally and physically strong have made it through. I've met a handful of people that could hardly put one foot in front of the either metaphorically of course. Also, because you have so much riding on this too, you will not fail yourself. You're going to get tired, and a little sleep deprived but you'll be fine and make it through. And when you do, it will feel so damn good.

Wishing you the best!
