With proper hormone supplementation, you really shouldn't have symptoms from your thyroid. Is your doctor doing just a TSH or also a free T4 and T3? TSH is the hormone from the pituitary that regulates the thyroid gland's activity. Free T4 and T3 are the actual hormones your body needs to function properly.
For initial diagnosis you should have had a complete thyroid panel, including the above plus thyroid antibodies. This may not have been done because transient hypothyroidism is common in the PP period. Are you seeing an endocrinologist, or is your primary or OB managing this for you?
It's a really good idea to ask for copies of your lab results. Then you can compare your result with the "reference range" the lab uses to see where you really are. If you can post these here, we can probably help more in terms of your thyroid.
That said, your symptoms do sound very much like chronic depression. Most people think you have to be sad if you're depressed, but actually irritability and anger are also common in depressed people. If your thyroid exploration doesn't yield an answer, you may want to consider counseling and anti-depressant medication. The birth of a child is a profound event in a woman's life and sometimes without knowing it we can be overwhelmed by the sheer responsibility of it all, or by it not being the fairy tale we always imagined.
Good luck to you, and please let us know how you're doing, Mom.
