The Sussexes and Cambridges have joined forces to encourage followers suffering from mental health issues to seek help.

Kensington Palace unveiled a powerful video to mark World Suicide Prevention Day today - featuring Prince William's national text crisis service Shout.

The video, posted to the Kensington Palace Instagram account, captures men and woman as they read out heart-wrenching messages like those sent to the service by people in need.

In the short clip, eight men and women share the stories of people struggling with suicidal thoughts, break ups, depression and self harm.

And just a few hours later the Sussex Instagram account shared a picture of a couple, encouraging followers to text William's crisis service, and writing: 'This World Suicide Prevention Day, we would like to spread the available support far and wide to ensure that no-one goes through a crisis alone.

'Please use or share the below accounts today, or on any given day, to a friend, colleague or even a complete stranger, that may be suffering - because wherever you are, you are not alone'.

The campaign comes a day after Prince William, who helped set up the service, revealed he hopes to train as a volunteer counsellor for Shout.

The Sussex Instagram account shared a picture of a couple, writing: 'This World Suicide Prevention Day, we would like to spread the available support far and wide to ensure that no-one goes through a crisis alone.'

'I give up, I've felt miserable for too long now and I just can't cope any more,' one woman reads.

Another says: 'It's my mum, she's got cancer. I'm trying to be strong for her but I'm scared and I don't know what to do'.

A third powerful message came from a person who was struggling with self harm. 'I've just cut myself again,' a woman reads. 'It's happening almost every day now. I want to stop but I don't know how'.

Afterwards, a man reads: 'I am sat in my car. I've been driving for hours. I'm so depressed. I just don't know what to do'.

One man reads: 'My girlfriend just left me. I love her so much and it really hurts. I feel so alone, I have no one to talk to'

Before the short video ends, a woman says: 'There are a thousand ways to start a conversation about your crisis. Shout is here for all of them'.

In the caption of the poignant video, Kensington Palace detailed how somebody in need could contact the service.

It said: 'There are a thousand ways to start a conversation about your crisis, @GiveUsAShoutInsta is here for all of them.

'Text Shout to 85258 for 24/7 support. Save and Share this World Suicide Prevention Day to ensure no-one goes through a crisis alone. #WSPD #WSPD2019 #Shout85258'.

The campaign comes a day after Prince William, who helped set up the service, revealed he hopes to train as a volunteer counsellor for Shout while visiting Harcombe House in Devon

The video was posted to mark World Suicide Prevention Day, just a day after the Duke of Cambridge revealed he hopes to train as a volunteer counsellor for Shout.

Visiting Harcombe House in Devon yesterday, Prince William, 37, spoke of his ambition as the service announced a partnership with emergency service organisations.

Chatting to volunteers from the service, which was developed by William and Kate's Royal Foundation, he said: 'I'm aiming to set myself up for it, I really want to do it.

'Even if I can only do an hour on my laptop. I want to do the training and be able to help.'

Shout volunteers receive 25 hours online training before being put in contact with members of the public through the text crisis service

Shout, launched earlier this year, is a free and anonymous service manned by volunteers, who can provide instant help, day or night, over issues ranging from suicide to relationship break-ups, as well as the effects of abuse or bullying.

Volunteers receive 25 hours of online training before being put in contact with members of the public through the text crisis service.

It was decided to offer a text message service as many, particularly young people, find it easier to message by phone than calling a traditional helpline.

If the situation is deemed an emergency with a real risk to life, it can be passed on to the relevant emergency service.
