Brief Answer:
You have 
hyperthyroidism & low calcium levels
Detailed Answer:
Hi XXXXX,
Thanks for consulting us.
Regarding your reports, Your blood complete picture seems alright. Sodium, potassium & 
Magnesium levels are fine. Calcium is low. Thyroid tests indicate a hyper-functioning thyroid gland due to some auto-immune cause. Commonest is the Graves disease. Sub-
acute thyroiditis is a rare condition & Thyroid stimulating 
Antibodies are usually low in this condition. 
Both Graves disease & Sub-acute thyroiditis cause hyperthyroidism & need treatment.
In addition you are also having symptoms of an enlarged thyroid gland & hyperthyroidism. 
In your medical history you mentioned 
Gestational diabetes, I am wondering are you pregnant right now or it was your past problem?
Anyway, whatever the cause you need further evaluation of your neck & Thyroid gland by an expert physician. Your doctor will do your local examination & may suggest tests like Thyroid 
ultrasound or scanning & may be some blood testing to find out the cause of these elevated levels.
You will then need treatment to lower the levels & to reduce your symptoms. You will also need 
Calcium supplements to optimize your health.
So, plan a Physician visit as soon as possible. Also report to your Gynecologist if you are pregnant.
Please write back if you have any question.
Best regards.
