Jahmene Douglas has said he doesn't want to be seen as a "sob story".
Inspired by his own experiences, the X Factor runner-up, who finished second in the singing competition to James Arthur, is a youth ambassador for domestic abuse charity Women's Aid, who he donated profits from his single Titanium to.
"I got annoyed when papers said I'm a 'sob story'. I didn't want people going through the same thing to define themselves as being closed, miserable and sad, they should be happy and in control of themselves. People need to know I've switched the negative into a positive and am raising money for a good cause," he said.
Jahmene and his family entered into a witness protection programme after his father Eustace was jailed for abusing his mother Mandy.
"I wanted to get involved because of what I've been through. There are so many things that need to be done and aren't being funded by governments," he added.
The former supermarket employee, who used to work in a Swindon branch of Asda, said he has now settled into his own skin.
"I've become more comfortable in who I am. The real Jahmene is probably a little bit unhinged and probably needs therapy, but I'm happy," he said.
"I came from witness protection and not being able to do things and go to parties. I was one of those kids that was just inside all the time, so to go from that to TV cameras in your face, it was intense. I wouldn't change anything though, because it's helped me grow to who I am now."
