Do I have ADHD and an Eating Disorder? Please help me.?

I'm a 13 year old girl. And my parents don't believe I don't have any disorders. I always move alot and always lose attention in school.. it's really hard. I always can't stay still and I always think I'm not tried. I was a very immature girl when I was younger but I was smart. 11 years old where I was in 5th grade I started wondering about my weight. I thought I looked fat. & decided to go on a diet. And some food I eat I end up throwing up.? I cry almost every night. And right now I'm obessed with food, even when I'm full I can't stop eating. And in the middle of my meal, I would just start running around the house. And I'm a straight A student, but I started going down cause I have trouble memorzing stuff in school. Please help me? Do I have ADHD and a Eating Disorder? Cause I read online that guys mostly get ADHD and girls most of girls eating disorders.. and that girls that have ADHD risk getting eating disorders when they reach teen years. Someone help me.! My parents are no aware of this, and I look at myself and think I'm fat.! Another problem with my body is I have scholisis( however you spell that) it means that my spine isn't growing straight it's going sideways.
