Weight loss

Just a quick rant- I have been working my ass off and haven't lost a pound. I have cut my calories and I have been doing zumba 3-4 times a week, as well as running and walking. Have I met the metabolic curse in turning 37? I refuse to buy new clothes until I can get back into them. What's a girl to do? Stop eating? Exercise after every meal. I refuse to turn to drugs to lose weight, or go back to the weight doctor when I know what I need to do to get it off. It just isn't leaving!!! UGH!
