Get t4 free and t3 free and another tsh test. As well as prolactin and estradiol and cortisol as well as another T test (you need at least two).
Will help to diagnose what you need
I'll be a little more clear...nobody can really say you are hypopituitary with those labs. It is possible but there are many explanations. Your TSH is normal, yet you have symptoms of hypothyroidism. So maybe your thyroid hormones are low yet your pituitary is sending out enough signals to your thyroid to make more hormones. This could be a back up to there being something wrong with your pituitary. Prolactin may be high which could be suppressing certain pituitary secretions...so there may be other things wrong here.
