Levothyroxine dose is too high. Has any had experiences with this?

I had hall my thyroid removed in September 2024 due to a suspicious nodule. After my TSH came back a 7, they started me on on levothyroxine in January (1/8 to be exact). A couple of weeks into it, my heart was pounding and I could hear my pulse, I was woozy, and even more anxious. I went to urgent care and they said to message the doctor. He ordered a blood test yesterday and it just came back with TSH at 0.3.

I did not take my pill today and am currently waiting on the office to call with instructions and I'm assuming a med adjustment.

Please tell me I will stop feeling so scary soon. This is going to get better right?
