Blood Test Results Excellent, But I'm Tired

My blood test came back with these results: Leukocyte count 5.4;

Hemoglobin A1C 5.1 Range 4.5-6.0
RBC 4.08 Range 4.0-10.7
Hemoglobin 13.4 Range 3.6-5.0
Hematocrit 39 Range 36-46
MCV 95 Range 80-98
MCH 33 Range 27-34
MCHC 34 Range 33-37
RDW 12.4 Range 8.0-18.5
Platelet 181 Range 140-450

Ferritin 47 Range 13-150

What do you think about these results? My doctor said they are excellent. Should I believe her?

Very often I feel low energy. Especially when I am at the gym. I am yawning very often during the day, even at the gym when I am working out. What does this mean?

Thank you very much for your time.
