it sounds to me like you might be having a reaction to the medication. The only way you can be sure is to go off the medication. That's what you should talk to your doctor about.
I would say depression, anxiety and meds.
Fatigue is common in both physical and mental health issues.
Just a thought, but is your office well ventilated. Working in a stuffy office can cause one to feel tired. More so I suspect if you have other health issues.
When I was first depressed I think I could easily have slept 24/7. I think fatigue is normal for someone who is depressed.
Did your doctor look for iron deficiency as well? My GP says anemia and iron deficiency are different. My iron levels are quite low at the moment (hence my inability to concentrate on posts, etc).
Cold hands and feet could be Raynard's. I think it is said to be made worse by cold and emotions. Cold intolerance is also a symptom of iron deficiency.
Blood pressure changes, visual problems, etc could all be associated with the medication.
Visual disturbances can also be caused by anxiety. Hyperventilating can lead to blood pressure changes.
I've been itchy lately. That's said to be a symptom of anemia. It's summer here and there have been a lot of annoying insects around so it could be due to them too.
I'm not sure what it is so I just put it down to anxiety.
The doctor will be better able to answer your question and allay your fears.
