Brief Answer:
consider free T3
Detailed Answer:
Hello and thanks for your question.
It is hard to say what exactly is going on. Your labs do look normal. There can be many causes for depression, cold sensitivity and inability to lose weight so make sure you doctor knows that you have these symptoms. The only blood test I do not see is a free T3, so you might ask your doctor to check that one. Occasionally a patient will have a normal free T4 but have problems converting it into the more active T3 and the best way to check that out is to measure free T3 directly.
I hope this is useful to you and I hope you are feeling better soon
