I can't see that you reported E2 levels and if you do, that needs to be in context with what your protocol was at that time. Labs should be done when protocol has been steady for a few weeks. "very low estradiol"
You should list labs in a list format, not in paragraphs.
Amount of anastrozole: Need to see labs and know the dosing. You might be an anastrozole over-responder [needed 1/4th expected doses].
Low E2 levels can cause libido and other problems. Target is E2=22pg/ml
Have you read the advice for new guys sticky?
If T3 is too high you will be hyperthyroid [loss of libido]. Body temps may be too high and heat intolerance might happen. You could be jittery, like too much coffee. Please check body temperatures.
Some of the symptoms of hyperthyroidism include nervousness, irritability, increased perspiration, heart racing, hand tremors, anxiety, difficulty sleeping, thinning of the skin, fine brittle hair, and muscular weakness?especially in the upper arms and thighs. More frequent bowel movements may occur, but diarrhea is uncommon. Weight loss, sometimes significant, may occur despite a good appetite (though 10% of people with a hyperactive thyroid experience weight gain), vomiting may occur, and, for women, menstrual flow may lighten and menstrual periods may occur less often, or with longer cycles than usual.
Thyroid hormone is critical to normal function of cells. In excess, it both overstimulates metabolism and exacerbates the effect of the sympathetic nervous system, causing "speeding up" of various body systems and symptoms resembling an overdose of epinephrine (adrenaline). These include fast heart beat and symptoms of palpitations, nervous system tremor such as of the hands and anxiety symptoms, digestive system hypermotility, unintended weight loss, and (in "lipid panel" blood tests) a lower and sometimes unusually low serum cholesterol.
Major clinical signs include weight loss (often accompanied by an increased appetite), anxiety, intolerance to heat, hair loss (especially of the outer third of the eyebrows), muscle aches, weakness, fatigue, hyperactivity, irritability, high blood sugar, excessive urination, excessive thirst, delirium, tremor, pretibial myxedema (in Graves' disease), emotional lability, and sweating. Panic attacks, inability to concentrate, and memory problems may also occur.
