Help with calorie intake

ive recently began recovering ffrom an E.D since over the holidays. I gained alot of the weight back but now it seems it just keeps adding up. i used this website http://www.bcm.edu/cnrc/bodycomp/bmiz2.html and it said i could eat 2780 cals, seeing i work out almost everyday for over an hour.

i was just curious to if that seems logical because even if i ea 1500 i always feel like im still gaining, which i really do not want. ive even been weight training with atrainer 3 times a week and doing an hour of cardio each day.

Feeling like you're still gaining is a different thing to gaining....   If your energy needs are 2780 (and that's very possible if you work out for over an hour a day) and the scales show that you're still gaining then it could be that your weight has not yet reached its natural healthy level.  The minimum BMI to aim for if you're recovering from an eating disorder is 20.  But a BMI of 20 - 25 is healthy and people who are very muscular and do weight-training are usually in the upper half of that range.
