Help with my appearance?!?!?!?!?!?!?

I have a lot of self esteem and confidence problems and I am very shy. I basically let myself go and I need help getting back to looking good and fitting in. I am 5 ft 6 inches, I am in 8th grade and I am 130 pounds. I stopped wearing my weird and outdated aeropostale clothes and I stopped hiding under my sweatshirt. I started wearing American eagle, hollister, Gilly hicks, and abercrombie & fitch. If u could please help me with wearing makeup, hair, and clothes basically my overall appearance. Thanks in advance!!
