Wolfy has been at the centre of ongoing rows about cigarettes in the house, primarily because she is unwilling to share her stash, which she has saved up.
Speaking in the Diary Room about her anger at the situation, the 20-year-old said: "I think there are some very ungrateful people and tomorrow at nominations I am going to be very penalised. Everyone is going to be gunning for me, even my best mates.
"It's just a mental mind f**k. It's depressing me. I don't want to sleep in that bedroom, I don't want to."
Crying in the Diary Room, she added: "I have never been in a situation such as this, Big Brother. I have never surrounded myself with negative people. I have never surrounded myself with people who get a thrill out of seeing people suffer. I think it's disgusting."

Later, she spoke to Hazel O'Sullivan about the situation, commenting: "I've just got so much anger, frustration inside me. I'm letting other people in the house change me. I don't feel like I can be true to myself.
"It's the one thing I said I would never let happen, to let people change me. And it already has happened... Listen to me; I'm being bullied in here by one person and you're best friends with him.
"He constantly interrogates me. He questions my life. He wants to know everything. He disrespects my family. Then he disrespects me. He makes me feel this f**king low.
"And now I feel like I'm physically possessed by this demon of anger and rage, it's not who I am. It's not who I f**king am and please don't say anything.
"I know you're friends with him, I can't deal with it. All I want is a f**king fag and I can't even do that without people being on my back. Because I was the only person clever enough to smoke three fags a day I am being penalised for it. I can't deal with this."
Big Brother continues this evening on Channel 5 when the latest round of nomination results will be revealed.
