Personne anémique prenant des comprimés de fer depuis 2 mois se sent toujours mal et les niveaux de ferritine sont pires.

Hi all, I (31 year old male) have been experiencing fatigue brain fog, generally feeling unwell for probably 7-8 years. Ive had MRIs and all sorts of things always finding nothing. A cbc did indicate Anemia around 3 months ago. Iron profile came back with Ferritin at 33L. I have since been taking 2- 325 Iron pills a day for just over two months. Over all im still exhausted/ brain fog and overwhelmed with anxiety or stress almost all the time with perhaps an ok day or two mixed in over the months. Just had another blood test done in preparation for a DRS appt and most of my levels have corrected but my Ferritin has gone down to 22L an my Absolute Lymphocyte count is slightly low (1.15). Any idea if this is normal or what would be causing this? Thank you!
