Failed an interview and started stuttering more.

Failed an interview and started stuttering more. In the month of January i was doing great, i was speaking fluently, without stuttering, i was feeling great because i'm in summer vacation, made some friends on Discord to speak English with, and i was also applying for jobs because i want a job to buy things that i need. I got an interview for a job that i really like and i really wanted to start, but i failed, and after that i started stuttering more. My biggest stuttering problem is that i struggle a bit to start my phrases (it depends on what i'm saying, like, if i'm want to ask something to somebody and i don't feel very secure i will probably stutter). But yeah, it's very annoying. I don't know how to control my emotions to be the same as before and be more stress-free but anyways, always that i know that i'm going to stutter i prefer not to speak instead. TLDR: I wasn't stuttering too much in January, but i failed and interview and i started doing it again in February.
