This week to jumpstart my loss I'm staying in the lower end of my acceptable calorie range. I'm sorry about all the stressors you have going on!
Just try to remember that good healthy eating will give you the energy you need, your father the nutrition he needs and your son both the nutrition he needs and the example he needs. It's always helpful to me in the beginning to remember how much energy I have and how great I feel mentally while I'm eating well. It's hard not to stray back into those old habits, but that is helped a lot by coming here. Good luck.
