Hi, I don't think your work mates will judge you in the way you think they will. They have all been in your position before, as a young person just starting work and will remember what that was like, and that it takes time to get used to work meetings, speaking out in front of others etc. If you could voice your nervousness then I think that might be weight off your shoulders and you may find that your colleagues become very supportive to you. Lots and lots of people struggle to speak out in front of others, this is very common but it does get better with time and practise. Maybe you could find ways to practise doing that in small steps until your fears start to diminish? It could be worthwhile seeking advice on the internet about this. My advice would be not to avoid these meetings, but to accept that it will feel difficult now but get better over time if you persevere. All the best.
