It's not just mental health which needs to become a topic less shunned in today's society, but many others as well. I have been diagnosed over the past years with PTSD, as well as DID (Dissociative Identity Disorder), both of which are a consequence of my intersex condition.
Or more specifically: the traumatic events resulting from the abhorrent treatment of my intersex condition by doctors and psychologists, who insisted I had to be transsexual instead, attempted to force me into 'normalisation' surgeries, lied about results and so on for more than a decade. Funnily enough I only tried to commit suicide once in all that time.
This is a common thing for those who are unlucky enough to be born intersex, and there are many more 'conditions' which are prime candidates for causing severe depression and the risk of suicide if not handled correctly. Homosexuality has more or less left that stage in most countries now, as well as transsexuality, due to increasing knowledge and acceptance of something which is actually natural, and not a disorder (as some are trying to rename 'intersex' into now...).
In short, society needs to stop bullying people with whom is nothing wrong. Just like how bullying at schools has led in the past and will continue to lead to suicides, so does bullying by society in general result in the same.
