I would advice just push yourself when you need to speak with someone, don’t try to avoid it. And more practice with people, I prefer 1 to 1. It’s hard and scary yeah What about the future with stuttering, many people easily understand that you have speech issue and can wait. I’m 26 IT specialist, every day I need to speak with team and others. Each interview to a new job I’m really stressed and stuttering a lot, I warn the people about my problem before starting interview. Of course, someone can reject you as a specialist because of your issue. But you really want to work with these people? Anyway you will find you path, work, real ties
