Lindsay is threatening to end her life if she has to carry out her 90 day jail sentence! Her entire family is so worried that they have Lindsay on a 24 hour suicide watch!

Lindsay Lohan would rather kill herself than be locked away in jail. The 24-year-old actress is reportedly so upset over the 90 day jail sentence looming over her since July 6, that she’s threatening to take her own life.

“She just kept repeating, ‘I can’t go to jail,’ and, ‘I’ll kill myself first,’” a source tells Star magazine. “She’s mentally unstable and getting worse.”

After Lindsay’s discovered she’d be serving time at the Century Regional Detention Facility in Lynwood, Calif., Star reports she went home and broke everything in sight.

“She ran around breaking mirrors, cutting herself and rambling like a lunatic. She tore her house apart before she finally just broke down,” reveals a source. “Lindsay’s on a 24/7 suicide watch, it’s so bad. She isn’t doing well with this.”

Not only is Lindsay going around saying she wants to kill herself but she’s taking a lethal dose of prescription drugs.

“She has been doctor shopping across the country,” she says. “She is utterly unable to control her use of any mind-altering substance.”
