severe anxiety most likely is causing your jittery feeling and overenergized. not your thyroid levels
you need to talk your doctor about mediations to treat your anxiety symptoms.
going on 125 for a few days would not cause you to be hyperthyroid.
you shouldn't be concerned

and you need to get on some treatment for your anxiety symptoms to help
