Let's just take the discussion away from the personal for a moment. And from this particular case as all we know is what is written in the article. And that is not much.
There are clearly strong feelings on all sides especially from those with personal experience.
Some posters have said how relieved they are that the discussion is out there.
The fact that Emma killed herself changes the way we see her life; it defines it. And we forget the life.
Many people suffer the consequences of living with a parent, child, sibling who makes life hell. For years everyone suffers through violence, rages, absences, unpredictability, lies, being let down, humiliation, constant negativity. (Obviously this is only some illnesses - some do not impact on families very much at all - and the person who is ill suffers most - that is clear)
The "advice" varies. LTB, go NC, she/he is abusive, toxic, save yourself, put your kids first. The degree of mental illness involved is not always clear - indeed it may ebb and flow. Depression can be manageable for long periods and then force a crisis at certain times.
There is also advice on how to help, on NHS resources, on books to read or therapies to try., money and time to spend on helping. And frequently it is futile and you know it. Year after year.
Should you, can you, be angry, abandon this person in order to save yourself and other family members?
If however someone has committed suicide the judgement of others on those left is that they should have done more, they should have been more understanding of the illness, maybe even that they "caused" or "triggered" it. Yet the difficulties of dealing with that person during life, for years, are unrecognised.
Not by everyone - but it is not uncommon.
to all those suffering from mental illness and to those who are close to them
