See your doctor and share what you're experiencing. I felt similar, and my PCP ordered:
- full bloodwork to test for everything like anemia, diabetes, thyroid, mono, and even celiac (after I mentioned I feel so much better on a grain-free diet)
- sleep study (this was a 2 night test in a lab--1st night is to record how you sleep, 2nd night if needed is to fit you for a machine)
- non-nuclear stress test (this is because my blood pressure is low, and I mentioned I get lightheaded while working out if I change altitude, like going from push-ups to jumping jacks)
For me, everything checked out fine. I was shocked, like seriously? I'm not even anemic?!?
Right now I'm recovering from pneumonia (I was hospitalized in mid-January) and I'm experiencing REAL FATIGUE and it's no joke. Before, I felt tired and lethargic and didn't want to do anything but nap in my free time. Now? HAHAHAHA. I'm lightheaded and ill, dizzy and slightly queasy. This isn't tired, this is GIRL YOU'RE SITTING DOWN NOW! as my body shuts down. I will be thrilled to go back to my old "fatigue".
Some things to try as you make an appointment with your PCP:
- Cut out grains and processed foods, and see if this helps you feel better after 1-2 weeks. At first you're going to feel terrible, but after a few bad hangover days, you should feel a new lightness and energy.
- After work, don't go straight home. Stop at Target (or similar) and walk around the entire perimeter of the store just once You don't have to buy anything--you're there to walk. Lean on the cart if you're feeling really exhausted. Give it a week and see if that little side trip helps you to have more energy in the evenings.
- Eat more. Sounds weird, but if you're trying to lose weight you might not be fueling your body enough. Eat a snack at 4 pm before you leave work (peanut butter on an apple, a protein bar, etc.) and see if that makes a difference in your evenings. If you're starving yourself at work, by the time you get home and feed your body with a large dinner, your body is going to be like, FINALLY! WE HAVE CALORIES! QUICK, SHUT HER DOWN TO SLEEP SO WE CAN PACK THESE AWAY FOR THE NEXT FAMINE!!!
Hang in there! I can so, so relate to everything you're going through!
