I can’t even say my own name sometimes, and it’s destroying me inside

I can’t even say my own name sometimes, and it’s destroying me inside I don’t even know how to start this but… I just want to talk to people who really get this. I’ve had this speech block / stammer problem since 4th or 5th standard. Now I’m 20, and it’s only getting worse. It’s not just stuttering — it’s like sometimes my brain completely freezes when I try to speak. I can talk with my mom, dad, or friends (with a lot of stammering), but sometimes, even when someone just asks my name, I can’t say a single word. Like my whole body tenses up, I try to speak but nothing comes out. Even answering a phone call from my mom, I pick up and then just… can’t speak. I know people say “don’t overthink, be confident,” but they don’t understand — it’s not about confidence anymore, it’s like a speech block, something stronger than willpower. I took speech therapy for a year (around 2 years ago) but didn’t see any real improvement. Now it’s starting to destroy my confidence. I’ve stopped giving viva exams in college because I can’t speak in front of teachers. I already got backlogs because of it. Everyone around me says “just try harder” or “relax,” but they don’t know how it feels when your own name gets stuck in your throat. People here talk about dating or relationships, but honestly, I’m not even thinking that far. I’m just scared about how I’ll survive — how I’ll get a job, how I’ll talk in interviews, or just earn money when I can’t even speak properly. It’s not about being shy or nervous, it’s about feeling trapped in your own voice. And the worst part — no one really understands. If anyone else here goes through this same thing — not just stammering but full speech blocks — please reply. I just want to know I’m not alone in this.
