I’m sorry, but I disagree. Depression IS an illness. In my case, my psychiatrist told me a long time ago that, with my family history, I ‘never stood a chance’. My illness is predominantly inherited and has nothing to do with state of mind or past trauma. The only treatment for me is medication - proven recently in a change in (non psychiatric) medication causing me to spiral into a MH crisis within a matter of days.
Of course, for many, there is a link to past trauma and/or what’s going on in their lives but that’s not the whole story. Please do not tell other members it’s ‘all in their mind’. Not only is it untrue, it’s also extremely unhelpful - and can make people feel they’re making it up.
