I agree with
@et81. I don't think a forum post can "accurately" convey your condition to the audience. What you are getting is a variety of opinions based on a one paragraph description of a highly subjective situational set of feelings. If you have not seen a medical professional about any of this, then I doubt you lied on DoDMERB. In addition, the fact that you earned an appointment shows you have achieved much in your young life thus far, in spite of your concerns.
Military men and women all feel anxious in combat conditions, so some anxiety under those circumstances is normal and expected.
However, the bottom line is that if you feel that you would "act out" or overreact due to your condition, then you should seek professional help and let the chips fall as they may. Only you can answer this question and you have a duty to do what is right.
