Super stressed with work, having a hard time maintaining my fasting

Hi everyone,

I was given a diet plan from a nutritionist and metabolic Dr. that involves fasting 2 days a week (3 Owyn protein shakes allowed on those days) and ~1100 calories on other days. I have lost 6 lbs in 6-7 weeks. The last 2 weeks have been rough with work (high stress and travel). I wasn't able to complete my fast, I got shaky and moody and had to eat food. I feel so disappointed in myself and like I'll never get back to where I was. Does anyone have any tips or tricks for high-stress times?

Thanks so much!
