I do not understand why your doctor will not treat your thyroid. If any doctor said that to me, I'd find another doctor.

With your talk of getting T3 via mail order, you seem to be self treating. NO ONE should ever self treat with thyroid hormones--that's why they are Rx only in the US. You can easily kill yourself with the wrong dosage.

All your symptoms could be traced to low thyroid, so you need a doctor to treat you ASAP.
