The worst irony about mental illness is that social stigma denies what MI sufferers need the most -- compassion, understanding, and support not only during periods of distress but throughout their lifetime. MI is not only a disability, its a disability that demands you act like you're completely fine. This is an irony that frustrates me so very much.
I think that it should be up to your daughter in regards to how much information you choose to disclose about her condition. I would ask her how she would like you to talk about or explain what she is going through.
