Welcome @tamazahriel
I know what you mean about freezing. My brain goes into a zoned out zombie fog when there's something I don't want to hear, so I have to wait a bit and hope I can decipher it later. Mostly I just ask to be given information in dumb terms please :)
If you can access a breast care nurse definitely get on board with her. They are brilliant at decoding the language for you and can be a really helpful liason between yourself and the surgeon if you are too worried to ask questions.
You learn pretty quickly that you are your own best advocate along the way. If you are not happy or don't understand please please say so and always ask what the choices are. Sometimes we feel there are no choices, but there may be alternatives.
Best wishes lovely.
