I'm sure you're fine. You could go to a few of those calculators that measure height/weight/age on-line for other opinions. Don't forget....your body frame and other things also count and they often discount those types of things in those measurements.

If you deem that you DO need to lose a few pounds, don't start purging or starving yourself again; you've made too many gains to go backwards. Come up with a sensible way of losing it. Getting a little bit of exercise that you're not getting now may be all you need to do to shed a few pounds.
