Mike, 26, took his own life last week, police confirmed, with his body being found in a North London park.
Mike’s family and friends gathered in Edmonton on Thursday evening to light sky lanterns and candles in his memory.
Those closest to him shared videos of the emotional moment on Twitter, which shows loved ones lighting their lanterns before letting them fly.
Sharing one short video of the vigil, his friend Michelle, wrote: “For @mikethalassitis.
“Goodnight @MikeThalassitis Catch those lanterns in the Sky”.
She also posted a picture of a huge array of flowers resting by a tree, alongside scattered tea-lights and pictures of Mike and his friends.
Some even pinned letters on the trunk, including one, which featured some touching words about depression.
“People that keep trying to find a reason why someone is depressed etc have never understood neither themselves known anyone suffering,” it read.
“You can get depression even if you have all the money in the world and life is looking good and on the up – it’s an illness that takes over your mood and thoughts”.
It went on to address Mike directly, writing:
“I feel like you’ve definitely impacted the world on a positive level – as well as shocking many and causing sleepless nights, I think this can help save other lives in future.
“I’m just sorry we couldn’t save yours.”
In light of the tragic news, ITV bosses have announced they will be making serious changes to its aftercare programme.
Richard, creative director of ITV Studios, wrote:
“When something so awful happens we naturally enter a period of soul searching and ask whether anything could have been done.
“This review has led us to extend our support processes to offer therapy to all Islanders and not only those that reach out to us.
“And we will be delivering bespoke training to all future Islanders to include social media and financial management
“The key focus will be for us to no longer be reliant on the Islanders asking us for support but for us to proactively check in with them on a regular basis.”
Our thoughts are with Mike’s family and friends.
