Oh dear @Dh5Wy83 this is hard isn't it. I have felt like that too. Once I lost it at someone and cried they did my ultrasound.
A stupid girl without inexperience got to me because she asked me if I did breast examinations. Was she kidding I almost did a breast examination every day after bread cancer. I was lying on the ultrasound table with my lopsided breasts. Shit I couldn't believe it. I was weeping but angry too.
My answer to her was to asked that girl what she would do in terms of a breast examination if she had breast cancer. She didn't know what to say and so she asked me again. Was she serious. I gave her a death stare. She wanted to know if I wanted to stop the ultrasound. I said no but I wanted a different person to do it. That happened and the owner of that business got feedback. Funny I have never seen her again.
If you are feeling people are inappropriate and sick of being polite try saying what you want and see if that works better for you. Giving feedback is a good way to vent too.
