FFS I'm fat again

So I think I am fairly sure I know what it isn’t ! Day 3 I feel a little euphoric as I start to loose fluid I suppose. I am several pounds lighter and I am waking earlier. My mood has lifted, I am smiling more. I am ready to face the day.

So am I chasing this feeling ? Do I put on weight in order to feel good when I start to diet again ? I know for sure this is absolutely not the reason why I start to put on weight again. So whilst I still work towards finding the answer I know for sure its not to chase that euphoria as I diet again.

However the difference in how I feel today compared to Sunday night is HUGE. I know that it is a mindset but what triggers that change ? Sunday I felt like I was walking through treacle, I was beyond tired and yet 3 days later I am full of the joys of spring and ready to seize the day. So what changes first the body or the mind I suppose that will be the answer. Is it gaining weight that sparks the change or a change in mood that sparks the eating. Is it the joy of indulgent food that makes me eat for pleasure or the chemical reaction to sugar, fats etc that sparks a change in mood that makes me eat in an effort to feel better ? Do I have a low mood and lift it with food ? Or is it purely accidental as a few little pounds creep on bit by bit that changes how I feel ?
