@ Aerogal ... This may be an unfashionable or transsexually-incorrect opinion, but if I could have been given a magic pill when I was in my early adolescence and first experiencing the pain and confusion of Gender Incongruity, that would have saved me decades of heartache and made the lives of my wife and children far easier and happier too.
@ Pebbles ... I don't know what you mean by 'invented' psychiatric conditions, but as a parent whose daughter almost died from anorexia I have to tell you that there is nothing invented about that terrible condition at all. The fact is that no one knows what causes anorexia, nor is there any real cure for it, other than somehow keeping the patient alive and bombarding them with care until - with any luck - they find the strength in themselves to begin a process of personal recovery. Personally, I was struck by the similarities in my daughter's experience of body dysmorphia to my own experiences of gender dysphoria. The significant difference, of course, is that the cure for anorexia means overcoming the dysmorphia, whereas that for GID involves acknowledging and acting upon the dysphoria. In both cases, of course, the most important consideration is just keeping the patient alive. Both conditions, after all, have a strong suicidal component and/or risk.
