Help How to hide my mental health?

[Ociv]

I am going to be enlisting in the army soon. I have heard that they pay special care to your mental health and behavior. I have had bouts of mania and depression all my life along with suicidal thoughts.

Any tips for how to hide these things from them? What kinds of questions will a recruiter ask and what kinds of responses/behaviors will they be looking for? I am good enough at acting, I just need to know what to avoid doing.
