Air Force and their rules on suicide?? help please?

Ok I am 20 now and I have already talked to a recruiter when I was 19 and all that was left to do was to be sworn in BUT i told the truth on one of the questions because I am honest and apparently dumb. It was about the counseling question and I said yes. Well they said that is the only reason I could not join because I had told my counselor that i had attempted suicide but the reason I was even in counseling was because I was in an abusive relationship with a guy! So them saying I couldn't join because of that made me mad. My now ex that was abusive is in the army has been hospitalized several times and has gone AWOL 3 times 1 of those was when he was on leave from Iraq he also has failed his drug test so it irked me that I was not able to join and I am honest and hard working. My recruiter tried everything even had me write a letter and in the end they said if I had finished my counseling then it would have been different. So I am curious if I go back to counseling for a while and they clear me what are the chances I can join? I was hoping to be a nurse. I am still going to college for nursing though I would just love to be in the Air Force. Any help is appreciated.
