Congrats on getting the job! However the interview went please be proud of what you’ve done. You’re braver than so much you think you are. Nothing to be embarrassed about when you tried hard and overcame your struggles to make this decision. I have a tip on this, not sure if it’s gonna be 100% working but I did this during my school years when I had to pronounce things start with vowels. Instead of trying to push out a whole word, just tried to pronounce that first letter, exp. Like Ariel, start with just “ahh”, just think about starting that single sound, may take a little longer for that sound alone until you have a flow to be able to say the rest. Happy weekend, don’t overthink, you did great. 😊
