'High thyroid' must have meant the TSH is high -- meaning the thyroid function is low. This is not uncommon post-partum. Check thyroid antibodies (ie, may be hashimotos) and the levothyroxine should be adjusted to keep TSH around 1.0
Hi -
What they probably meant is that your TSH level is high (that's a measure of how loudly your body is screaming for more T4. A high TSH equals low thyroid activity (or vice versa - a low TSH equals high thyroid activity). Your symptoms are pretty common in hypothyroid patients. I had all the same symptoms as you (and I am hypothyroid). Don't worry, you will get better on the meds.
