The key to helping depressed friends and fellow teenagers is to listen patiently and be supportive.
That is the message delivered by the Youth Suicide Prevention Project, according to the students who took part in the campaign.
It is organised by the KELY Support Group (KELY), Outward Bound and the Samaritans.
A group of 12 teenagers joined the project in July. They attended training workshops dealing with what depression is, how to identify the signs of suffering and how to cope with the situation.
They also attended a seven-day leadership camp run by Outward Bound Hong Kong and made several presentations at schools in Hong Kong.
One of the participants, Stephanie Tang, a Year 12 student from the Australian International School, said it is quite hard to pick up depression signs.
