Lying at meps about mental health

I'm in a little pickle. I was suppose to go to MEPs to take a psychiatric evaluation based on the fact that I was in drug classes Well I was waiting for doctors order from MEPs to see if I was going to have to take it Needless to say I am positive I am going to have to take it. I was admitted, willingly into a psychiatric ward I want to join the service but this is kinda making feel like I have something to worry about. I already have in the system Told my recruiter that I never was he put it into the system that I was never institutionalized.
