Belly fat :(

So I am losing weight pretty well and not finding it difficult to eat right or exercise. My rich friend gives me clothes all the time and she' s given me some and they fit except in the belly area. I am hoping they will fit better when I loose another 15-20 pounds but WHAT IF THE BELLY FAT DOESNT GO AWAY???!!! I lost weight before (I used adepex and gained all the weight back) and the belly bulge was still there when I had lost the weight. Is there something I can do to make sure that I slim down in the stomach area??!!
