Need LOTS of Help (lol)

[#1]

Hello,
I am young-ish and my mom started letting me wear makeup recently. My mom doesn't ever wear makeup and I've never worn makeup before either, so we both didn't know we were doing when we went into Sephora. I was looking for an eye concealer. One that would hide the terrible bags I have under my eyes. (I think I have these bags because I play volleyball and practice can run up to 10 at night! And then I have to wake up at 5 am in the morning to go to school. So, Im always tired and have big, dark circles under my eyes. I asked the lady at the front desk if she could help me find something for it, so she showed me "Sephoras corrector lenue et perfection- lasting and perfecting corrector." But it only makes the lines more defined under my eyes!!! It makes them look worse!! Is it because of the way Im putting it on or is it the Corrector?? 
So long story short-too late- I am looking for something that will make my dark circles go away completely. I also don't want it to clog my pores up or cause me to break out. I would like something all natural or organic if possible. 

I also bought "Sephora's Dying for fudge N 60" eye shadow. But I don't like how it blends in with my skin and makes it look like I got a spray tan, but only right above my eye and not on the rest of my body. So, do you guys know of any good eye shadows for Blue Eyed Girls?? Im not sure what "Complection I have" because Im new to this. But I DO know that Im NOT tan, but Im NOT Pale!
Also, for a girl whose mom wont let her get black mascara...is there such a thing as brown mascara?? 
Thanks in advance!!! Sorry for the really long question/story!! I promise ill make it shorter next time.

Something that would probably help a lot is a corrector underneath your circles.  I have really fair skin and when I have circles, I tend to use Bobbi Brown corrector with Laura Mercier secret concealer on top of it.  Another idea would be a brightener, such as YSL Touch Eclat.  If it's settling into lines, what I've found works well is making sure you have enough eye cream used with your skincare before you put any makeup on.  Something else that works is taking a TINY bit of eye cream if it settles and tap it over the concealer.  However, if it's caking, you might be using too much.  Where it needs to go is in your inner corner of your eye socket where you can see blue/purple/brown, and just under the inner corner.  If you extend it all the way out underneath your eye, it can look like you're wearing too much.  A concealer blending brush, such as Sephora's Pro Airbrush Concealer Brush, is a great investment and I use mine constantly. 

For eyeshadow, Urban Decay's Naked or Naked 2 palettes would probably be perfect.  They're all neutral shades that almost everyone can wear and are really pigmented, so you really don't need a lot.  Theyre also designed to blend with any color in the palettes.  If you want sheerer eye shadows, Clinique makes eye trios and quads as well as singles, which are which I started out with when I started with makeup.

As for mascara, a lot of companies make brown mascara.  Clinique has some great mascaras that are available in black and brown for about $15 or so. 

You didn't mention if you're wearing foundation or not, but if you're lucky enough to get away with it, Sephora's Tinted Moisturizer is $21 and works great to cover minor imperfections and even skin tone.

I hope this helps.
