Being shy

Merron
Hi everyone, so I could really do with some advise. I'm am super if not stupidly shy but I just can't get over it. For exemple in class, even if my name is mentionned I start panicking, sweating, looking people like ''Why me? What about them" I just wished that I wasn't so shy. I don't want to be really outgoing but I feel like I'm limited, I can't just go and speak to people and it seems, whatever I do I just can't get over it. Does anyone have any advise or does anyone feel the same?
