So my psyhologist gave me a workbook to do. It states here, verbatim, "behavioural symptoms of anxiety: hyperventilation (you: check), pursuit of safety, reassurance(you: check)." You searching up all medicals conditions to contextualize your difficulty in breathing is a form of reassurance seeking and safety behaviour. Honestly as hard as it is, you ought to wane yourself from googling otherwise you will only prolong anxiety and harm the effectiveness of your treatment. Instead of googling, try to focus on something calming like she said. So perhaps focus on the changing colours of the trees or even other drivers and delay your need to google. OR just simple remove your access to your phone by putting it away since technically it's illegal lol. I know because I got pulled over and he gave me a warning ticket for $450.00.
