From personal experience; I found that when feeling depressed or irritable,this is the time to stand back and take a look at "YOU".
I have recommended and did for my self these rules:
1- Make a list for me!
2- Track my water intake.
3- Eat a good healthy breakfast..no excuses.
4- Have my fresh fruits for snacks and keep them handy.
5- Take at least two 15 minute breaks every day,walk,exercise, get your blood moving.
6- Always have a nutritional dinner.
In our busy lives of caring for others,we forget ourselves. STOP and think about YOU. You would never send your child out the door without a lunch if you knew they were unable to be fed.
This is what you are doing to yourself. You are expecting your body to run on nothing,but to provide everything.
The old saying stands true...you are what you eat...if you fill your body with bad carbs, and no good nutritional foods, then you are going to eventually break down, becoming sick,depressed,and unable to care for yourself much less your loved ones.
Take a two week challenge....try drinking your water, eating a good breakfast, eating a balanced lunch, snack on those fresh fruits and vegetables and enjoy a nutritional dinner. Take those two 15 minute breaks just for you and move your body..what ever is best for you.
Then let me know how you feel!
