Is a 'personality disorder' a mental health problem or not?

[a girl]

Soz if that's a tricky Q or it really depends. It's just psychiatrist said it and then my mum's all, 'At least you don't have a mental health problem!' I'm not saying I want to be mentally unwell, but my mum is so keen for me NOT to be, to get off medication and out of the 'system' that it just annoys me. I never like asking questions to health professionals, lol.
