Don't beat on yourself !! Life happens !! As the old cliche goes,"don't throw the baby out with the dirty bath water!" You had a bad week. Things like this are going to happen. You do the best you can. Does that mean give up ? No, of course not.
One bad week will not derail any of your weight loss efforts. What to do is (to the best of your ability) return to your normal, healthier, routine asap. So, if you skipped your exercise, then you start up again tomorrow. Tonight, you eat a few extra servings of fresh fruit or veggies. You make sure you drink plenty of water.
Remember, this is a journey and there will be bumps along the way. Be kind to yourself as you would to others.
Don't worry ! Everything will be okay !!
