Far more common than you'd think, going by what people write. Your mind formed a whole self-picture around one specific body, and once the mirror disagrees it stalls. Logically you know you wanted this, feelings just trail behind. Shrinking doesn't fix how you felt about yourself earlier, and people expect confidence to arrive with smaller clothes, then feel let down when it doesn't. Nothing's wrong with you, years built that self-image and a short stretch of change won't erase it overnight. Those who cope best quit waiting for a new feeling and simply acted differently, wearing a top they like, letting photos happen. Feelings seem to trail behavior, not lead it.
