I only stutter when I speak to people, when I am alone and talk to myself, I don’t stutter at all and can speak well It’s so infuriating. My social anxiety has definitely made me stutter a lot. I can talk so well alone but not with people. Like I’m even struggling to speak with my own family members, that’s how bad it is. I seriously think my fear of stuttering began because I went into another country and spoke another language but my accent was off and people were making fun of the way I spoke so then I tried really hard to pronounce everything in a good way and it has made me become paranoid. Like I have never faced stuttering issues before I moved here. I can talk so well in English but when I speak thus language, i just stutter so bad and then when I stutter, my brain just stops thinking and I do not know what to say next… Even if i try to speak slowly, there’s that awkward forced long pause that happens between words and it’s so irritating…
