Sorry to hear of the stress this is causing you. Although we can’t be 100% sure that your T isn’t saying those words, we can be very confident that your T is not saying them. Here are some more or less objective things to consider:
*You mention that you were distracted
*You mention that you weren’t making eye contact. Seeing lip movements during speech can make a huge difference in comprehension. Check out something called the McGurk Effect
*You mention that you have low self esteem and are a little paranoid. Given the above, these characteristics could be filling in the auditory blanks/lack of clarity in a not so nice way that matches your internal feelings. Our brains do this all the time.
*Remember the yanny vs. laurel debate and how much people mishear song lyrics. Perception is not reality.
*Do you have any direct evidence that your T doesn’t like or mistreats you?
