What tools does a Buddhist have to engender others to take a wiser approach?

Mum is regularly woken in the night by panic attacks which bring on uncomfortable physical sensations that she takes so seriously she has been known to ring the paramedics (always unnecessarily). After many months I am still unable to get her to even entertain the notion of 'staying with the discomfort, just as it is'. Does a Buddhist have any tools (metta/prayer/mantras - sorry I don't know the words) to manifest/stir-up a change in someone else’s approach? Or do I have to work on cultivating my own acceptance of the situation - however resigned that might make me feel?
