I haven't been embarrassed but I have been intimidated so I haven't tried for careers I could have done, just because I lacked the confidence that was needed since both were professions - nurses and medical assisting, seemed to rely on hearing abilities. I don't think my lip reading skills are up to par even though some people have thought so.
I found it is more often funny as opposed to humiliating. Got a few stories where I thought they said and nope it was this... that resulted in some funny events/conversations. Humor always opens doors.
