diet forever???

i dont know if this will last forever, but i cant seem to get contented with my weight. i told myself before that once i reached 130lbs, im ok. i reached 130lbs but i wanted to lose some more. Now i am currently 123lbs and cant seem to get contented. i am now targetting 115lbs. A lot of my friends said that i should stop coz they said i am already thin...but honestly, i dont think i am. am i anorexic? hope not, i dont think i am, hell no. i still eat 3x a day, low carbs though. but everytime i look at the mirror, i still see a fat lady. how depressing. i hope this ugly feeling will soon fade. i am tired of this strict dieting but i cant seem to stop, i guess not now, nor in the future....
