I was stupid a while back. I cut back food, over-exercised and lost my period and became chronically fatigued. I'm eating a lot better now and I have my period back, but it has been MONTHS and I still cannot run. I have started to go to the gym 3 days a week and I am able to do that but cardio makes me dizzy and fatigued. I am fatigued doing daily tasks even like at work. I have had my bloods tested and they are fine and I take vitamins.
My sleep quality is also still extremely poor, I am lucky to get 6 hours in, despite good sleep hygiene and eating enough. I wish I had never done this to myself.

These are my recent results:
Red blood cell count: 3.78 (range 3.80 - 5)
Haemoglobin: 121 (range 120-165)
Haematocrit: 0.38 (range 0.36-0.46)

Strangely, my MCV and MCH were right on the highest end of normal, however.

I feel like I am dying, genuinely. I feel dizzy, I have severe brain fog, and I am so so so tired. I look exhausted and completely drained in my face.
