Stuttered my way out of a well-paid job opportunity. I hate my life

Stuttered my way out of a well-paid job opportunity. I hate my life Last week on Saturday I went to do a speaking test for a interpreter/translator job. By the odds it would be my highest paid job so far. Was a little nervous but quite mild from usual. Went to the offices, had a little chit chat with the guy there. Of course i stammered through saying my name because of course i did. Dude straight up asked me twice, he must've thought I had a hearing problem (😄🔫). Anyways I sat infront of the laptop, put the headphones in and started the test. I swear to you, I'm not trying to boast; I knew how to answer to every question, but the thing happened again. I stammered through the presentation part again, and then "hmm'd" and stuttered through the rest. It got me so out of it I was giving such short answers (which isn't what they wanted). I left the chair relieved and absolutely sure I wasn't getting that job. I got the message from them yesterday confirming the former, and while I didn't have hopes for it, it still stung. I feel very frustrated and incapacitated from this condition, not to mention I could really use some cash right now. Couldn't have been more ill-timed. Feeling very angry and disappointed. Thank you for reading.
