Yes, blood tests confirmed I missed a little bit of iron, took supplements and levels are now normal but the fatigue and dizziness didn't go away.

Thanks, it seems a lot of people have similar symptoms, hope some of the causes get better treatments, but also more recognition, feels awful going to work every day like this, and doctors not prescribing time off work because symptoms are to broad/vague and no life threatening illness is found. If I didn't have a family to provide for, I'd just stop working right now.
