I agree with everyone here - while it's discouraging to see a higher number, you still have lost all you thought you have! The tape measure is more accurate if you can remember how to get in the same place each time - LOL.
And you are STILL the same person, that looks great I bet, after losing 16 pounds! Your goal weight may be further away but remember that's an arbitrary number - you are going to look awesome by your goal date no matter the number. It's relative. Deep breath!
I am beginning to hate my scales - they are all over the place! So I'm right there with you. I was so proud to have lost 10 lbs as I'd scratched to it the last two weeks, minute little percentage by percentage. I announced in mini-goals, took a picture - told my family and friends...and then over last two days I've gained 3 - I'm back where i was two weeks ago and I haven't gone of the plan - even been incorporating MORE exercise. I want to cry, but I have to have faith right?
SO DON'T GIVE UP. THIS IS A JOURNEY! I WON'T IF YOU WON'T. Look at all those success stories and get inspired. You will make it to your goal too and be so proud you didn't give up.
