Definitely go and see your doctor. Have CBC done, so you are able to see what your hematocrit and hemaglobin are. I felt like that when I was SUPER anemic, and it literally made me tired to eat food because I had pretty much no oxygen in my blood which is already fragile from spherocytosis. Don't continue feeling sick and faint...see your doc. Keep us updated!
