Why can't I seem to lose weight?

I've been trying to lose weight for just over 2 months. I only eat 500cal a day and exercise everyday, but still not losing ant weight and waist is the same. I measure myself once a week an occasionally I've lost 1IB but then the next week it back.

I really don't know what I'm doing wrong. And somebody please help me?

I'm 35
131Lb
150cm tall
Waist is 38cm

YES I'm only eating 500cal a day and YES I'm adding everything. Why do people keep saying I'm lying when all I'm doing is asking for honest advice... wish I hadn't bothered
