I have always been honest about my suicidal thoughts when I have them because I'm honestly scared that if I weren't honest, I wouldn't get the help I needed. I have told my doctor that I think suicidal thoughts, but he asked enough questions to know that I wasn't having suicidal thoughts at the moment, and also that I'm open with my husband and alert him to those thoughts when they come. She should have asked more questions. I would never advocate lying about it, and if they ask they should expect an honest answer, but she should have clarified. Also, your husband should not have left you, regardless of how fine you seemed, until he could speak to you privately and really get a read on your mental state. What's the point of having a spouse if they won't take care of you when you need them?
