Could I have food addiction..?

i constantly think of food...all the time and always crave chocolate and all kinds of fast food. i hate my body with a passion, and i'll eat a ton of food each day then feel disgusting after and start crying alot. if i want to stop eating my meal, even if im full, i just cant. ill always attempt a diet plan and even if its just a simple one, it doesnt last more than a day. i always eat when im not hungry, just to satisfy the craving. i feel disgusted every time i overeat. my mom doesnt think i have food addiction, but i really think i do. i want to stop it but it's extremely hard. i couldnt eat completely healthy even if my life depended on it (which technically..it does) i'm a 14 year old girl
