What are professional responses to a partner yelling at you in person?

Or tips to fake confidence when getting yelled at? I have a partner that nothing I do is right.

She called and yelled at me yesterday and I had to hang up the phone on her because I was going to start crying.

I’m just nervous how to act in person now.

He undermines everything I do/say and as a new lawyer I don’t have a lot of confidence on what to say back to her .

What are some good responses that are still professional to say to an angry partner ?

I don’t have experience getting yelled at by people in law school. This is my first job since graduation.

Also is it normal to get yelled at? If so, then I may not switch to another firm. I will just quit practice for good.
