There are number of organisations that work towards helping young people with severe depression. These include Headspace, Beyond Blue, The Butterfly Foundation and Lifeline (Kidsline).
But sometimes support is found in a few words
Michael Leunig
Don’t fret too much for the Departed.
Even though they leave you broken hearted.
Have no fear
They WILL reappear
When you’re alone and unprepared
They will just turn up. Do not be scared.
Be still. Do not turn away;
There is something wise they have come to say
To you and to you alone;
Some plain and simple thing already known
They will touch you and say,
“It’s alright, everything will be OK”
Or something just like that, short and clear.
Then casually they will turn and softly disappear
Leaving you elated and in perfect peace
The meaning of life and death will then increase
And your love for the departed one will grow.
There is so much more you will get to know
About love that is unassailable.
So long as you make yourself available.
