I’m nearly 23 myself and have social anxiety although not as bad as it once was. You’re need to accept that you need help and that’s ok, it will take time. The reluctance of addressing the problem is actually worse than the problem itself, people who have a speech impediment like me and the other wonderful people on the sub often fail to realise this. I was like this for long time refusing help because I didn’t actually want to address the problem. A few tips for you; 1. Self-Affirmation: when you get up in the morning or just before you have to leave for work or school say positive things to yourself in the mirror: “My stutter doesn’t define who I am” / “I have the right practice my speech and overcome my stutter”. This will help tremendously 2. Practice: As they say, practice makes perfect. Any technique you pick up, try it out and stick to it. If it doesn’t, move on to give next one. Go outside and talk to strangers. Ask simple questions like “excuse me, do you have the time”, “could you tell me where X store is please”. Or go one better and tell them you’re a person who stutters and your here to work on your speech. I know that would probably scare the shit out of you and did to me but the more I went out and approached people I started to enjoy it and did it more often. This really helped with the social anxiety. OP, hopefully you will take this advice on board and best if luck in your journey. If you want to have a further chat just DM me.
