Anorexic or no?

Alright I'm eating around 1500-1600 calories currently. I've lost a total of 55lbs over the course of 1 year I weigh 175lbs and use to weigh 230lbs. My parents think I'm anorexic and my skin is pale and that my flabby skin/ fat is abnormal. Oh, I'm also 17 years old about to turn 18. Exercise is at a minimum, which I know will contribute towards some of the flabby skin, but I still can tell that I have fat left mostly in my abdomen. Another thing is when I suck in my gut my ribs show pretty bad and that gets them worried but as soon as I exhale my belly seems pretty big still with fat. Any help would be great on whether you think I'm anorexic also if it'd be better with pics let me know I might just ask this agian with some pics.
