It can be incredibly surprising and disappointing how people can react to mental health issues, even just hearing that you have them despite not presenting symptoms at the time.
A prior acquaintance of mine was a social worker who helped people with such conditions live (semi)independently. One in particular hated his medication, but when he wasn't on it, he'd become increasingly paranoid that vampires were out to get him. To the best of my knowledge he was never violent, but you're right- when imagining defensive paranoia, popular media always brings to mind a loose cannon who might be a danger to themselves and others.
In time, this may change, but I can't say that I'm too hopeful. We no longer associate menstruation with hysteria, but it's easy to change when we're talking about half the population. So long as fictional media outnumbers real lives, it'll be harder to change.
With that said, change comes from learning, and I hope your sharing will help others understand.
