How can I help my depressed student daughter who is miles away

DEAR DEIDRE: Worrying about my depressed, drug-taking daughter is affecting my own mental health.

She lives 200 miles away at university and I don’t know how to help her.

I’m her 49-year-old mum, and she’s 20.

She’s had mental health issues for several years, and I was so relieved when she seemed so much stronger before going to university.

But since breaking up with her boyfriend last autumn and getting involved with a boy who has a chaotic life and does drugs, she’s gone downhill again.
