Physical health issues.? help me please.?

First off. i took a look at my body and a pot belly is growing in faster than i thought. im constantly eating when im not hungry and when i am hungry i try not eating. my friends say im turning anorexic on them and that im in denial. i don't know what to do.. second i went to my pediatrician lately and she gave me cream and moisturizer with sun screen for my face. i have an apt. in a few week and i am terrified that my acne won't go away. also is there any cure for deep marks that were left by pimples? it'd be helpful. Now we get to MY HAIR. i shower every few days because when ever my hair is fully clean it gets all frizzy. my natural hair is frizzy and curly so i use a hair product called Chi to get it strait. Today was the first day i used it and it DID NOT work. and the only other option i have is Frutis frizz control and that does nothing for heat. please help me im desprete and trying to make myself look the best i can. my look is my health and i care for it just as i do my grades. i try to impress the boy i like as much as i can. we are total oppisites and hes gorgeous and im just okay. i need to change my ways and put myself out there. help would be the best thing anyone can offer me. id really apreciate it :) please help me:) i need all the help i can get <3 i have issues with my mental and physical health. i
