lucy the term borderline refers to the fact that the disorder falls between personality disorder and mental illness. It doesn't mean that it is only a 'borderline' (ie not genuine) disorder.
I'm glad your daughter is not suicidal. Does she self harm in any way? That is very hard to cope with and as I'm sure you know people who self harm are not necessarily suicidal - rarely so in fact, though they sometimes kill themselves accidentally.
Good luck.
Relatively new here so an introduction.
I loved my mum, she was the best.
