“I JUST WANT TO CRAWL INTO A HOLE and hide!”  KIM KARDASHIAN’s worst nightmare as worsening psoriasis threatens to destroy her looks!

Stressed out over her increasingly bitter split from estranged hubby Kris Humphries, Kim Kardashian is facing her worst fear of losing her looks as her skin disease spreads over her body!

She’s terrified the red, scaly patches on her legs will spread across her back, hips, torso and arms and she will no longer be able use make-up to hide them.

The ugly patches are caused by the chronic auto­immune disease psoriasis, and now sources say the fallout from Kim’s failed marriage could make the condition explode, wreak­ing havoc on her career, her health and her self-esteem.

“Turning from ‘Beauty’into the ‘Beast’ is Kim’s worst fear,” said a source close to the “Kourtney & Kim Take New York” star.

“The stress of Kris’ charge that their marriage was a fraud isn’t helping her condi­tion, and she fears the crusty red spots caused by her pso­riasis will spread.”

For now, 31-year-old Kim’s psoriasis outbreak is limited to her legs and stomach and she is able to hide the irri­tated areas most of the time, according to the source.

“But it’s very painful, especially when Kim lies in bed at night,” the source added. “She’s afraid that the spots will soon cover her body and has cried over it a few times.”

Psoriasis speeds up the growth cycle of skin cells, which can appear as thick, silvery scales and itchy dry red patches on the skin.

The reality TV bombshell was di­agnosed with the disease this past sum­mer. Her mother Kris Jenner suffers from the same condition and experts say high stress levels can contribute to outbreaks.

“The exact mecha­nism of stress causing psoriasis to flare is not completely understood, but the link is well ac­cepted,” Dr. Rebecca Baxt, a New Jersey-based board certified der­matologist, told The ENQUIRER. “Certainly, a quick mar­riage and divorce could raise anyone’s stress lev­els and aggravate their psoriasis."

Kim is consumed with worry that her “brand” will take a hit from the implosion of her mar­riage as well as the toll the psoriasis will take on her near-perfect looks, insiders say.

“My career is doing ad campaigns and swimsuit photo shoots,” she ex­plained on an ep of “Keeping up with the Kardashians” when she received her diagnosis.

“People don’t understand the pressure on me to look perfect.”

As she faces the possibility that the disease will spread, the source said Kim wailed to a friend: “My legs look hideous! I just want to crawl into a hole and hide.”
