One of the most awful things about the Caroline Flack post about mental health was where she said she had tried to talk to a friend who had said she was "draining".
This is one of the most awful things about mental health crises: its difficult to admit to it but the plain truth is that people going through mental health crises are often very hard to be around, often to the point where they are potentially damaging to others, and quite often their nearest and dearest decide to pull back to protect themselves.
When my former husband was having a very serious health crisis which involved several suicide attempts thankfully unsuccessful I tried very hard to support him because I knew he had no-one else -- even though he was frightening me. Ultimately I had to seek an injunction against him to protect myself. Although I had to do it for mine and my daughter's safety it felt awful to have to abandon someone who I had been very close to for a decade when they desperately needed support.
That's a fairly extreme example, but the reality is that supporting people in the grip of a serious mental health crisis is no walk in the park and the rhetoric about "just being there" can be a bit facile and simplistic.
Its often not as simple as just listening to someone. It can mean just listening to someone repeat the same thing 20 times a day when you're trying to do a job or look after a child. It can mean having someone turn up at your house in the middle of the night, drunk or generally in a terrible state. It can sap all of your time and energy and leave you feeling very depressed yourself.
Of course we should all reach out to show people we are here to help. But this is missing the bigger point which is that as a society our understanding of and ability to treat mental health problems is primitive. Leaving aside the questions about the media/social media and the role they play in these situations as that's a whole other topic, mental health needs serious investment and a huge step up in medical and social provision. Just saying "I'm here to listen" isn't enough.
