I have been so conflicted in my reaction to H's approach to discussing his own MH problems.
My DD (16)'s life is massively affected by mental illness, and has been for a number of years. One of the very few places she is able to go is a (charity funded) support group for young people with MH problems. The individual stories of many of these teens are heartbreaking.
Part of the aim of the group is to spread awareness, champion causes and fight for funding.
My DD and others in the group have spoken with the local MP, been interviewed for TV news items and fund raisers, visited schools etc. They talk about how their lives are affected, what has helped and who has supported them. As well as what support is still desperately needed.
When they meet as a group, they are able to share personal stories and day to day challenges and offer peer support.
Therapeutic support is undertaken individually and privately.
I can't help wishing Harry had approached his mission to open up in a similar way. It is entirely possible to discuss the effect something has had, without disclosing details of the event itself -(especially to the world's press!)
His approach leaves him wide open to prurient interest, criticism
of his account of events (which will be "his truth" not necessarily other people's truth), and hurt to others.
