I need MAJOR help! fast!?

Well, first off, relax. You aren't the only one. If you mean big girl as in a big boned person, then you will have to find clothes that play down the size. Stripes usually make people look more slender, don't wear stripes around, only up and down. And that in moderation, no one wants to look like a candycane. Wear long flowing skirts or sundresses and always a sandal with no heel. If you mean overweight, limit the portions you eat, drink water and exercise. Vasline Intensive Care or Palmer's Cocoa er with consistency, will fix the dry skin and flakes. Use it daily and especially in problem areas and be consistent with it. If your feet are very dry, saturate them with vasoline and wear socks to bed (feet models do this). Chapped lips can be a sign of dehydration, get on that water, and Vitamin D helps with your lips and then Nutrogena Lip Moisturizer, by the chapstick's. Same thing with the elbows, use those lotions and do it consistently, use a body er of Cocoa er for the elbows and knees and your biggest problem areas. Discoloration, you can buy an OTC skin lightener or if you wear make up, you should go to a local cosmetics store and let them match you, tell them what your facial skin is like and they can help you. Most everyone's arms are darker than their legs. Even this up by tanning, in a bed or naturally. My knees get really dark so when I lay out, I put a towel over that part. If you have to, to even it up, lay out and cover your arms or put a strong spf on them and not on your legs. Just be consistent with everything. But none of this will work if your not serious and follow through with it.
