Leaving in less than a month. Need advice

Hello!! I leave in less than a month now for basic and then AIT.

I’m scared out of my mind. But I ultimately know that this is what I want to do. I passed everything at meps, and I even passed the AFT to get a higher ranking. Still, I’m nervous that I’m not going to be strong enough to pass and graduate.

Can anyone share their experience, and any advice? I can’t shake my nerves no matter what. Every night I can’t sleep due to anxiety about leaving. I chose 12N as my MOS.

Thank you and happy holidays :)
