Recruiters told me if I went to the military for what they wanted me to, I would be able to do it because I was being medicated at the time (early high school, 6 years or so ago) for bipolar, even though they wanted me to for decryption.

Medicated or not. You would be denied, unless you tried to lie your way through it. Depending on how severe your condition is.

I'd just like to thank you for your service, I've wanted to enlist ever since I was a child and respect all that serve.
Currently, I still have two more years until I'm able to enlist.
Of curiosity, what branch were you enlisted in?

I have been in a few branches. Most of my time served has been with the Infantry. I've also been a combat medic. I prefer Infantry than that though for obvious reasons.
