Luke Anderson
The 39-year-old business owner - who won the TV series in 2012, after revealing he was transgender - received deaths threat over social media following his success on the show.
He said: "I was new to Twitter and little did I know how nasty it could be.
"People threatened to stab me, said frequently that I was a freak and didn't deserve to live.
"I began to suffer really badly with panic attacks, the ambulance was called one of the times. Thankfully I learnt to grow a thick skin, and realised that these trolls were just after a reaction."
Prior to entering the 'Big Brother' house, Luke only told his family about his transition from being a woman called Laura to becoming a man.
But the TV star was overwhelmed by the positive reaction he received when he chose to discuss his transition with his housemates on the show.
Luke told The Sun Online: "My work colleagues didn't have a clue about my past, I was 'stealth'.
"I was so sick and tired of having to hide my past. I decided that if I went on the show I could come out and help other people who may have been in the same boat. To be a visible trans man on TV.
"I was very nervous. I became so nervous I just felt numb on the launch night. I was expecting the response to be mixed, but when I told them I was overwhelmed by all the positive responses, it was very emotional."
Luke also admitted his time in the 'Big Brother' house now feels like a "mad dream".
He said: "It's an experience I will always remember, sometimes I wonder if it ever really happened or if it was just a mad dream.
"The time in that house made me realise who I am, the good and the bad."
