height and weight

currently i am 5'6'' tall and 115 pounds. my dietician says i need to weigh 118-130 lbs, so my question is, what do people around 5'6'' usually weigh? is this a normal weight range because it seems high to me. i feel like i could just stay at 115 and be fine.

but then again, i used to weigh 85 lbs so it's obvious i have a very distorted image of myself...any input?

tessa- thank you for the advice, you are right. today i restricted my snacks and felt AWFUL. i had obsessive food thoughts all day and it was ridiculous. so then i made up for it with my night time snack and i feel much better and decided i just really need to follow my meal plan...weighing less wont make me happier, i just need to find BALANCE.

bsh- i agree with you, thanks for the advice.

jcl76- very reassuring! if only they would let me exercise :/ hah but you are definetely very in shape and i wouldnt feel bad pushing my weight if i looked as good as that. thanks for the insight!
