I have only one idea for you Nick..............GET TO YOUR DOCTOR!
While the dizziness COULD be related to anxiety, your other symptoms just don't jive........most especially this "split tonsil" thing!
You need to have these issues looked at as soon as possible. I don't mean to scare you, but they just don't add up to anxiety in my book.
Please let us know how you're doing, OK?
Peace
