Steroids have no effect on the thyroid.
It's possible that the symptoms that you have are thyroid related, you need to run TSH, FT3 and FT4 tests to confirm this, do you have the results of the tests that you done? if so, then please post them here with reference range!
Once on levo you will need to adjust your dose several times until you reach the proper dose for you, this can take a while, adjustments are done each 6 week to three months, but once your TSH stabilize, you will start to feel better.
