All the rigors of being a professional model have Kendall Jenner rumored to be ready to walk away from it all.

Hollywood Life reports the never-ending pressures to stay skinny and slim have the teen rethinking her career path, with the thought of perpetually dieting starting to impact her more than ever.

"Kendall is feeling immense pressure to stay model skinny," a source said of Kim Kardashian's younger sister. "Although Kendall has been blessed with amazing genes, she still has to diet and restrict what she eats to stay as skinny as she's supposed to walk on runways and be in high fashion magazines. It's really hard on her and sometimes she just feels like quitting all together."

The 19-year-old Jenner spent part of the summer hanging out with all of her sisters, and being around the younger Kylie so much was particularly hard on her.

"Kylie eats whatever she wants and rubs it right in Kendall's face," a source added. "They will go out to eat and Kendall will order some Kale with only lemon juice as dressing while Kylie will order a pizza and ice cream for dessert, laughing the whole time at her sister's misery."

The freedom to eat whatever she wants whenever she wants isn't the only thing Kendall reportedly envies about her younger sister.

"Kendall is really jealous of Kylie's freedom when it comes to her hair," a source added. "She can go blue for a while, blond, put it in cornrows, dreadlocks and cut it however she likes. Kendall has been told that designers and advertisers really like her long straight black hair and that she shouldn't mess with it. She won't get the top notch modeling jobs if she has bleached or blue hair."

Kendall recently indulged herself by briefly sporting a blond wig, but in a matter of days her hair was back to normal.
