The pressing on your head did not cause anything other than a surface irritation. Your anxiety has turned it into a multiday waste of your time and emotional energy. You seriously need to find someone who can teach you anxiety reducing skills. Your life will be miserable unless you can get control of your anxiety ridden thoughts.

You also need to learn to just trust people who are more knowledgeable then you. You don't appear to have the reasoning skills to properly understand concepts like this. That is understandable. Not many people can grasp the complex issues of G's forces and pressure. So, please try to stick with the hard boiled egg analogy. It is probably the best way to understand the pliability of the brain.
