can low ferritin make you feel like you’re dying?

so my hemoglobin, saturation, iron, etc are all in the middle of normal. however, my ferritin is literally 11. my doctor just tells me to eat iron rich foods, but i feel like that isn’t helping.

over the past year i’ve had to leave school and my job because i’m dizzy 24/7, can’t stand for long, and feel like i’m blacking out. i can’t think anymore, my hair is thinning and i can’t gain weight. i do have low bp too, but was perfectly fine with my treatment until my ferritin got worse. all other tests are clean too.

i feel like i’m losing my life to whatever this is. is this normal? how do i fix low ferritin when everything else is normal?
