I feel you. Talking on the phone is the worst for me. I prefer so much more talking in real life because on the phone I never know what they‘re thinking of me or if they‘re laughing at me. I have a hard time getting my name out and it is so embarrassing. I am working in therapy specially on my self-esteem and confidence when talking. I‘m always worrying about what people are thinking about me and my anxiety makes my stutter sooo much worse it‘s ridiculous.
