Fatigue

Ladies I'm 12 weeks and the fatigue is taking over my life. 😢I have hardly any energy by the time I get home from work. I have a two year old and my husband is in school full time. I've tried to fight through it, but it's so hard some days. What do you do to help build up energy?? Any foods I could eat that would help?? Please oh please help! I feel like such a terrible wife and mother. I need some direction on how to get through this.
