High thyroperoxidase antibodies (TPO) is indicative of Hashimoto's, or autoimmune thyroid disease - basically hypothyroid. But in early stages we can swing from hypo to hyper
Your GP seems to have confused it with Graves' disease
Read as much as possible about Hashimoto's. Hashimotos commonly affects our digestive system leading to low vitamin levels
Before seeing endocrinologist Ask GP to test vitamin D, folate, ferritin and B12. Common that these are too low
Neither of the sets of results you've given show any evidence of hyperthyroidism. All the Free T4 and Free T3 results you've given are below mid-range. If you were truly hyperthyroid these would have been high.
The fact that you've had these low in range results AND your TSH is low in range make me wonder if your pituitary is capable of producing sufficient TSH for your needs.
However, there are other possible explanations for the results you had. You may have been just coming out of a Hashi's flare. The positive result for TPO (Thyroid Peroxidase) Antibodies shows that you have Hashimoto's Thyroiditis (known to patients as Hashi's). I don't know whether you knew you had this but there is no doubt. I've described what this means in practice in the third reply to this post :
There is another thing to consider. A lot of people who have thyroid issues develop low or high cortisol. There is a lot of overlap in symptoms between these two conditions, and amongst them is anxiety, depression, panic, palpitations, fast heart rate, insomnia, weight changes. Also, with high cortisol there are effects on the thyroid - TSH is lowered and conversion from T4 to T3 is impaired. (I'm not so knowledgeable on low cortisol symptoms.)
The propranol you've been prescribed may make you feel better temporarily, but they are not good for your thyroid and they don't cure the underlying condition (assuming your cortisol levels are wacky).
The best test of cortisol levels is saliva testing. This can only be carried out privately at your own expense. If you decide to do the test, once you have the results you can post them and ask for feedback.
I think this test is the best one because it includes a test of DHEA along with cortisol :
