Thank you for your service. I would not disclose that information to them. You are ok now and that is what matters. They aren’t going to ask you to provide medical records. Your past is your past and you have obviously recovered some from that period in your life. Don’t be one of those people that are too honest. That’s personal information to me and none of their business. Just provide your overall health history. In nursing, you need to have all of your senses like sight, hearing, smell, etc., be generally healthy, and able to perform physical duties. You will also need to be emotionally and mentally stable. We all know ourselves best so go be a nurse.
