When I was in boot camp at the "moment of truth" I confessed to having depression as a teenager. I want to re-enlist in the Airforce will it mess with my choices for jobs?

First, change your profile. Had you completed Recruit Training, completed your contract, and received your Honorable Discharge, you would rate being a Marine Veteran/Prior Service. But you are not, so square yourself away.

Second, an USAF recruiter can answer the second part of your question.

Ah man!!! Didn't your recruiter tell you not to crack at the "Moment of truth"? Anyways the best thing you could do is ask a recruiter as HollywoodMarine has suggested. I honestly have no clue on that issue, and most of the people i knew that did crack created havoc for themselves and their recruiter.

The Military is hurting for numbers the only way to find out is go talk to a recruiter, worth a shot.
