I am a TOTAL girly girl, and I'm being forced to go camping! Help!?

Ok, so I am 14 and a complete California city girl. Im pretty normal for where and how I live, but my best friends mom signed me up for this camp and i am TERRIFIED. She is like a second mom to me, and she is a really pretty businessy designer, always super on top of everything and I have known her pretty much my whole life, I alsways just say she is my aunt, she is always does sweet stuff for me. But she thinks camping is good for you and this year she signed her daughter (my friend) and me both up. And she payed for it and everything, so im kinda stuck. And I'm really worried I don't think I am cut out for this. It's like a week and a half long girls camp, in the woods, the wilderness. I think you sleep in like tents and dirt floor log cabins. And hike and cook over a fire and all that stuff. I have only camped once before but it was not a good experience! And that was when I was like 10! I hate dirt and bugs. And I am so worried their won't be bathrooms or mirrors, or that we wont be able to shower or we will have to pee in the forest. I mean, I take a hot shower every day, use shampoo, conditioner, soap, shave everyday... i also have had some trouble with acne, and I use a special facial wash and body wash as well as medication on my face and back every day to control and prevent acne. I wear contact lenses too. And I wear kind of a lot of makeup. Most days I wear foundation, a little blush, lipgloss, some subtle eyeshadow, and mascara. Even on a light days I wear concealer and mascara and lip balm or something on my lips. I usually straighten my hair, sometimes I curl it or braid it or style it up. I wear stuff like skirts and jeggings and sandals or heels or boots, lacy scarves, earrings. This is a camp for teenage girls who are really into camping and backpacking entrepenering (is that a word?) and stuff like that. I am going to be a fish out of water. I mean three of my friends are going but they are all athletic and dont wear makeup or anything. None of my girly friends are going. PLEASE, advice on how to camp for girls?!?! How do you manage it? Thank you so much?
