Got rejected in the HR screening round

Got rejected in the HR screening round A friend referred me to his company, and I received a call from HR. I do stutter, but I still answered all the questions they asked. Later, my friend told me that HR spoke to him and said I stuttered a lot during the call, and because of that they won’t be moving forward with my profile. Now I feel extremely sad and completely lost. I’m not sure what to do next, because it feels like my work skills don’t even matter if I’m not able to speak fluently.
