I commented on thyroid, ferritin, B12 and folate 4 days ago in You need some form of thyroid replacement. It is low thyroid hormone which is making you feel ill although ferritin could be higher.

VitD 74 is adequate if you can get some sun on your face and arms during the summer. If not, supplement 1,000mcg vitamin D3 which should be taken 4 hours away from thyroid medication.

HbA1c is negative for diabetes.

Sodium, potassium, urea and creatinine are within range so normal.
