PLEASE HELP! This is the 100th time I am trying to lose weight!

Zimushkaa

Hello everyone! My name is Ana Katarina and I come from Paris, France. I just turned 19 a week ago.
Three years ago, I lost a lot of weight and had a normal BMI.
Last year, after breaking up w/ my ex boyfriend, I started gaining weight like crazy and went back to the point where I started, more than three years ago.
The only difference now is: I am scared of not being able to lose it all.
I seriously want my BMI 23 again and trying to face reality, once again!

I am now eating a full protein diet, where I usually eat around 600-700 calories per day (like I used to do before).
Hopefully, I will be losing 10% weight wise of my total body weight.

How are things happening for you?
Cheers!
