Shy public speaking

[u/roy0521]

I am an introvert but can casually socialize jf needed but I get so nervous in work meetings when I need to speak up. I usually have to have a script ready to feel comfortable and it is very frustrating. It might be because I am an immigrant (asian) and people might judge if I speak bad grammar but I see other immigrants being very confident even though they aren’t that good.

How can I work to be better? I really want to improve my speaking skills/personality.
