According to TMZ, Punk obtained a restraining order against his mother who threatens to kill herself if he doesn’t give her money. Punk filed the restraining order “due to repeated financial demands and years of abusive, harassing and threatening behavior.”
Also from the TMZ article:
In the document, Punk says he’s made an effort to help his mom — who he claims suffers from bipolar disorder — giving her more than $100,000. But Punk says her “abusive/threatening behavior” escalated when he cut her off.
If you remember Punk’s DVD, he talked about moving out of his home when he was younger and living with his best friend. He’s also been very vocal about his father’s alcoholism as being part of why he chose his lifestyle. He mentioned that his brother stole money from the wrestling federation he created early in his wrestling days.
