Excessively tired?!?

Zerenity • 28. Arizonan. Army Wife 💍
So, I don't know what's causing this but the fact I'm quitting my job, and moving. I can't seem to find my energy! I've cut down soda, fast food, and bad foods by 3/4. I usually try to drink as much water a day, however; I'm not getting any energy. I get rest at night, but I feel like it's not enough. I don't drink energy drinks or any of that. Can you ladies recommend anything? I don't want to have to see a doctor. /: 
Thanks.(:
