Don't worry. From the report you've shared, it seems you have hypothyroidism (low levels of
thyroid hormone). It is a condition which is easily manageable. You'll need medication for the same. The dose will be decided by the doctor who examines you and sees your reports. I'd suggest you see a general physician or an endocrinologist for the same.
Next Steps
Consult a general phyiscian or an endocrinologist.
