Not sure if you're still monitoring this thread, but thought I'd post a reply just in case.
I also have yellow skin around my eyes, mostly visible in photos, but enough in person that people will often ask about it.
Several people have mentioned jaundice and liver problems. Because jaundice would usually effect the whites of your eyes, and other areas of skin, it is highly unlikely that it is a liver issue. That said, you should definitely get a quick liver function test to rule this out, just in case.
One of the other common causes could be thyroid imbalance, mostly commonly hypothyroid (or low function). Thyroid hormone assists in processing beta carotene into Vitamin A, so the yellow could be beta carotene buildup. This might also cause some acne-like bumps on the back of your arms. Other symptom of low thyroid function are weight gain, excessive fatigue (though keep in mind a teenage girl needs 10-14 hours of sleep a night!!), and many others. This is diagnosed through a simple blood test.
Other things to check out are allergies, though traditional allergy testing doesn't give very specific results. If you have ever had hives, or have digestive issues, I would also check into testing your candida levels.
Hopefully this gives you some ideas to check out!
