Earlier this month, Jonny Benjamin began a campaign to find the man who saved his life six years ago.
"His act of kindness changed my outlook on life and I have thought about him ever since. I want to find this man so I can thank him for what he did. If it wasn't for him, I probably wouldn't be here today."
Jonny teamed up with mental health awareness charity Rethink to further his cause.
He appealed to people who might have been on the bridge that day to come forward with any information.
On Tuesday 28 January, Jonny was reunited with his saviour - Neil.
Since the day on Waterloo Bridge in 2008, Jonny has worked in mental health campaigning, and making Youtube videos, passing on the message of recovery.
