Anxiety

So I'm thirteen, and I've been having loads of anxiety attack sort of episodes... My tutor (who happens to be the school councillor) spoke to me about it and said that he wants to start seeing me frequently to help... This makes me more anxious than ever... does anyone have any advice on how to deal with this sort of anxiety thing? or do I need to talk to my tutor? Hate telling people problems, in the fear of being judged... Tips and advice please💛
