Wow, your situation is ironic! My career path was also in communications, but with a specific task. I can tell you that your anxiety is based on low self confidence. There are a couple good books I recommend, It’s Only Anxiety by Carl James and Hope and Help For Your Nerves by Dr Claire Weekes. I think you would benefit greatly from them. As a comm student, it would be a natural fit for you. I participate in a couple different forums and have had several people tell me that these books were very helpful. I use the method described in them and can honestly say it works.

Part of anxiety can be understandable fear. I am in a business that requires public speaking and similar communications. I had some substandard results. A few people gave me the old, you doing fine, blah, blah, but one said, you had a lot of pauses and uhs, why didn't you write your speech down. Hurt a little but tremendously helpful.

Preparation can help as does narrowly tasks. I don't do 15 different things but perhaps 3 and do them well and that builds confidence. .

I actually just learned chronic stress and anxiety affects communication and memory. So don't feel bad you are a communications major :)

Welcome to DS! Everyone here is so supportive and great.

The Claire Weekes book is so good, I'm reading it now and it describes everything about anxiety. It helps you rethink your thought process. I understand about public speaking also. I'm a musician so it comes naturally for me to perform in public. Try doing some music live or karaoke, that will help you. Hope you get better
