You are picking a goal that is almost underweight. So maybe you should start this time by picking a healthier and more realistic goal.
We all take breaks especially when life gets too intense. I am also coming back after a long break, having gained back ten pounds of the hard-fought loss that took me three years. We are all in this together and we all go through difficult times that set us back. But every single small thing you do to take better care of yourself matters. Every baby step is 100% better than doing nothing. Welcome back, and I wish you happiness and good health regardless of what the scale says.
