Dont loose hope man, breathe in and breathe in some more. Even if you dont say anything sometime silence is better abd actions are enough. Practice 15 min everyday and talk to someone really close to you( mum dad sis brother cousin) just tell them can they hear me speak for 10 mon per day, and tell them a movie you watch its story or some news article. Paraphrase them. It might help you. Stutter stammer as much as you can but also try to breathe in and say words slowly
