Hello, I Need Help With Information For My Mom Who

Hello, I need help with information for my mom who is 38 years old. She was a very healthy person, always exsersising, eating healthy, never smoke or drank or did drugs, but for the pst 2 months she has been complaining about severe headaches that cause a Sharp pain on one side of her head/brain. Sometimes she sees black, and feels very dizzy. And the pain in her head never leaves, it's so bad that she screams of pain. She has been multiple times low of iron and anemic maybe that could be it? That's what her doctor told her, but I'm seeking for other help too. Thanks! Please I am very worried and I am only 16;(
