It is clear from these results that there is something happening with your thyroid, because you are getting a gradual rise in the TSH which may not be much - in fact the variation could even be down to a variation in the time of day when the blood was taken - on the other hand it is a variation which seems to be steadily upwards. In addition, your T4 is low in the range and the T3 is not brilliant. When I had T4 and T3 at those levels I was feeling very ill too.
This suggests that although at the moment you may have what most of the medical profession would call 'subclinical' hypothyroidism there is no doubt that, coupled with your obvious signs such as raised cholesterol and puffy face, you are showing clinical signs of hypothyroidism. In the USA a TSH of 3 would give you the diagnosis.
Under those circumstances I would ask for a referral, and when you see your endo, make the point that there are different guidelines for different countries and mention the USA. Would you be able to see whoever you choose? If so, it may be worth emailing Louise Warvill for a list of endos to see, I'll ask her to give you the email address.
I do hope this will be the right way to go for you.
