What's wrong with me

I'm 15 I am 5,5 I use to weigh 127 but my fat went to my upper thighs and center tummy and I hated so I started dieting and now weigh 119 I only eat two meals usually for ex I ate a salad for lunch and steak soup for dinner and that's it but yesterday I only ate half a salad all day then went to sleep woke up went to school on a empty stomach and almost passed out I'm always cold and my skin turns pink purple with splotches but I'm still chubby what's wrong w me ??? Plus before any hate I am not starving myself I eat when I get hungry which is rare so I make myself eat so I don't forget
