Hey, Robert. Here's the deal (and I always say this to everyone!): I'm only a first year med student. I know next to nothing about thyroid/endocrine disorders. My standard medical advice is always--consistently and faithfully--to go see your own doctor.

I know you have an appointment in two weeks. What he/she will likely do once you've communicated your symptoms is order some bloodwork and check your thyroid hormone levels, your blood glucose and everything metabolic in between. Then he'll likely also ask you questions to screen for such things as depression, anxiety, fatigue/sleep deprivation, recovery from flu (which I know you've had), asthma/allergies, bad diet, vitamin deficiencies, and all sorts of other things.

From what little I know of thyroid disease from my friend Mary, who has low (hypo) thyroid problems, many of your symptoms would be at the other end of her spectrum and indicate overactive rather than sluggish thyroid, and you certainly do have several of them that are on the (high) hyperthyroidism list at the link below:

Hope that makes you feel somewhat better to see that link! Seriously, though, only a real, in-person doctor can diagnose you. One who can take a blood sample. Make sure you keep that appointment, OK?
