Yes, those results would indicate your thyroid is struggling badly at the moment. Your brain is yelling at your thyroid to make thyroxine (T4) which is what that high TSH is all about - a chemical "shout" - but your FT4 is almost at the bottom of the range so it's not working.
PaulineS, as you've had pituitary surgery TSH may not accurately indicate hypothyroidism. Nevertheless, TSH 6.27 is over range and along with low FT4 indicates hypothyroidism and you will benefit from Levothyroxine to raise FT4 and FT3.
