This type of "anemia" most likely will not show up on blood tests, it falls more in line with sub-clinical symptoms. If the conventional lab tests do show anemia then the progression of the condition has already grown in severe fashion.
I would recommend increasing red meat consumption from a safe, quality source. Also eat more liver. I would recommend adding a B-Complex with possible additional B-12 supplement, if already taking these, you may need to adjust the ratios or dosage. I would recommend ingesting more amounts of bone marrow. If you are very brave or crazy enough, try eating some placenta (not joking) for nutrient boost. Up to the individual how far one is willing to go to achieve their health targets.
If unwilling to try some of the above, some more classical food wise approaches are:
Daikon radish (personal favorite)
Spices: garlic, onions, scallions, turmeric, cayenne, ginger, cinnamon, nutmeg
Improve Blood Lacking
Dragon's eye fruit (personal favorite): Lychee or Longan
The increase in emotional response is trying to tell you something, that the spirit is off balanced and needs your attention.
Generally a stressful event or the build up of multiple stressors are usually key triggers to throw the emotions off balance.
Suggestions: mediation, yoga, deep breathing exercises, laughing
Sometimes the simple methods are the best healers. We do not always need to be so tech savy or innovative when it comes to personal healing. Eating food can heal, breathing correctly can heal, laughing can heal.
