Demi Moore's life is thought to be "completely in crisis."

The painfully thin 49-year-old actress was admitted to hospital earlier this week after suffering from a seizure.

Demi remains infirmed and is reportedly being treated for anorexia, among other "substance abuse issues".

Friends close to the star believe that her life is in shambles.

"Her life is completely in crisis," a source told Us Weekly magazine. "She is turning 50 and has no idea who she is or what her focus should be."

Demi has apparently hit rock bottom in many ways. The star is finding it difficult to cope with day-to-day matters.

"She has spiraled and gotten to a place where she is struggling too much to function," the source continued.

Demi is receiving support through the crisis from loved ones, including her dear friend Madonna.

"Madonna told Demi she was there if she needs anything," an insider revealed to E! Online. "They're pretty tight."

Demi was left devastated last year after reports emerged that her husband of six-years, Ashton Kutcher, had cheated on her on their sixth wedding anniversary. She announced soon after that she was ending the marriage but divorce papers have not yet been filed.

She is currently being treated in a Los Angeles medical facility.
