Contemplating to resign due to stuttering

Contemplating to resign due to stuttering I'm so frustrated and I want it to stop. To give you a background about me, I'm working as an auditor in a Big 4 firm in the US. Currently, I'm handling a bunch of staff and regularly communicates with the Client through Zoom meetings. I've had experienced mild stuttering when in a call or even face-to-face with the client but not as severe as today. Earlier, I had an important meeting with the Client wherein we discussed stuff about the audit. I had stuttering so bad that I just pretended that I had intermittent internet connection. Before I could even speak a word, I stumbled and said a lot of "uhms". Every word I said required me tremendous effort just to speak one syllable. Another thing that frustrated me is the Partner was expecting me to lead the meeting. It's really frustrating because my job requires someone who can easily communicate any issues to the client. I love my job. I really do. And I will do anything to be promoted as a Partner. But right now, I feel like I'm not fit for it. My stuttering is such a hurdle. Sometimes, I also think that maybe God is punishing me. I am a smart guy. I gained lots of medals from competing in sports, quiz bees and journalism. All I want is to speak fluently with unnoticeable stuttering I'm crying in my room right now, contemplating whether I should resign and just move to a job that would not require me to speak that much. It makes me cry because I really love and enjoy my job but because I have a speech impediment, I can't be that outstanding employee I aspire to be. Do you think I should resign?
