I am probably just one of the moms out here thinking:
Wow, I don't know you but I am proud of you!
You describe a very busy but wonderful family & life! You just need help focusing on your blessings. Feeling bad or guilty because your life is on the fast track just pulls down your energy.
One thing I can recommend to help you pump up your psyche is a gratitude exercise.
Every night before you go off to sleep recall 6 things from your day you feel grateful for. One for each sense plus one you feel in your heart. So it's 1) something that was pleasing to your eyes, 2) something that sounded good, 3) something that smelled good, 4) something that tasted good, 5)something that felt good to the touch and 6)something that touched your heart in a positive way.
You go off to sleep with all these good thoughts & feelings and it helps you wake up with & maintain positive energy. Do this for 3 or 4 weeks & you will see & feel an amazing difference.
