Hyperthyroidism

Hi There,

I think I am suffering from Hyperthyroidism.
Which I caused with sexua| exhaustion. It is causing me to have ED and PE problems

My test results.

T4 11.9
TSH 0.64

I am 25 years old.

How can I restore thyroid function to normal?
These results are after trying herbal remedies.

I am willing to try anything! Any help would be appreciated.
