Yes and no. The problem with trying to explain to someone who is mentally ill that they are indeed mentally ill is that they lack the ability to self reflect and view their own thoughts and actions dispassionately. Their brain isn't working properly, and the anxiety tap is open all the way, all the time. It's pretty common for people with lifelong mental issues to have to hit rock bottom before they can be persuaded to accept help... and for that help to be offered in the first place.
Convincing someone that they're unstable and paranoid is basically impossible, especially if they've had genuinely rough backgrounds and have been victimised in the past. "Yes, you've had all these people out to get you in the past but this time you're wrong." Good luck!
The problem with the "affirmative" mental health care model- for everyone, not just the gender confused- is that the emphasis is on being happy/euphoric and "safe" instead of functional and stable. Affirmative health care is worse than no health care at all, imho.
