How to manage continuous eye ache, headaches, and fatigue?

Hello doctor,

I was diagnosed with hypothyroidism two years back with TSH 7.45. SGOT 61.0, SGPT 42.0, triglyceride 241, cholesterol 220, LDL 125.8, HDL 46.0. The BT report a year back is as follows: TSH 8.38, T3 92.3, T4 6.75, SGOT 26.5, SGPT 30.24, triglyceride 188.85, cholesterol 215.61, HDL 44.32, LDL 156.6. Ratio 4.90. I feel a continuous ache in my eyes, headache, fatigue, become anxious easily, get a severe headache if exposed to heat. I get hungry every three to four hours. I have been doing exercise and yoga for last eight months. It brings slight relief in morning hours and by 12 PM fatigue sets in. I was taking Thyroxine 25 mcg for six months last year. I used to have low BP and low pulse, felt giddiness in evening and so reduced Thyroxine dosage to 12.5 mcg for last five months. I am not diabetic. Kindly advice.
