Yes. Your reports strongly suggest iron-deficiency anemia, and this can very well explain the persistent fatigue, excessive sleepiness and low energy.
Your
ferritin of 4 ng/mL is markedly low. Ferritin below 15 ng/mL is generally considered diagnostic of depleted iron stores, and values below 30 ng/mL are commonly used to identify iron deficiency.
Next Steps
Please consult a physician/gynecologist and discuss starting therapeutic iron supplementation rather than relying on diet alone. Oral iron is usually the first-line treatment. Ferrous sulfate, fumarate or gluconate are commonly used; once-daily or alternate-day dosing can improve tolerance.
Health Tips
I would suggest discussing a CBC with MCV/MCH/RDW, serum iron, TIBC/transferrin saturation, and evaluation for the underlying cause with your doctor.
