At MEPS I lied about something. What happens if I bring it up?

I would just like to say that you should hope that no one that knows you sees such a statement because lying to MEPS in order to get into the military is an offense that could have you immediately booted out of the military or, worse, jailed.

I wont echo what the others have said as they gave some great advice. This is something you have to decide for yourself. You basically have two crappy choices. You need to pick the one that you will be able to stare in the mirror at and live with. You have to be the one to live with your choices.

Regardless of the choice you make, you do need to seek treatment. I have known too many good people who didn't and ended up "opting out". Depression is a serious thing and like any medical issue it needs treatment. It will get worse over time if you don't deal with it.
