Anna, an Albanian asylum seeker, escaped a physically abusive home and an arranged marriage only to fall victim to a sex-trafficking ring.

She recalls being transported across international borders and raped repeatedly, until finally managing to escape her abusers while in the UK.

"I've been in a really dark place emotionally," she says.

"After everything, I was numb for many months."

Now living in London, she tries to remain positive by attending school and volunteering with children.

"When I'm around children, it's so joyful," she says.

"I totally forget about everything else that's going on in my life.

"My dream now is to keep teaching children... especially for children of immigrants or children coming from a domestic-abuse background like me."
