Feeling bad about myself

recently i've lost a lot of weight, i've been eating healthy and exercising so not been doing it the wrong way, but i've lost about 2 stone in like 2 months, which i think is pretty good.. i wasn't big before, but i've always been a little bigger as i had really big boobs and a big bum, but since losing weight i've lost my boobs and gone down like 2 sized, which annoys me but that's ok, the problem is that i'm not getting called unhealthy and i'm too skinny, i weigh 8 stone now, my family is saying that it looks wrong as i've always been a bit bigger, curvy, and now i'm not.. but i feel horrible about myself now when i thought i was doing really well
