Erm, maybe see your Doctor and maybe get a referral to a dietician?

Failing that, my laymans remedy would be to spend two weeks firmly ensconced on the couch, continually eating stodge whilst watching daytime soaps.

Relax . . .

Your body WILL change. (Wait until you hit the 40's)

What else is going on?

Do you feel OK?
normal periods?
all systems working?
What about your parents or family history? Are they also thin?
and lastly, how do you feel about food?

My math computation here says that you're 5 ft 0.5 in and about 108 lbs. Can anyone verify that? If so, there's absolutley nothing wrong with that as it's proportionate.

If this is the case, perhaps you are just worrier? is it possible you have a bit of a distorted view about body image?
