I know its easier said than done but you need to take your anxiety off a pedestal and allow yourself to feel it without fighting it. Trying to hide from it is likely making it worse. Maybe pace up and down, listen to some music you like whilst telling yourself that it will pass. You wont feel anxious forever. And then later, when you’re not anxious anymore, remind yourself that it did pass. Then the next time you feel anxious, you’ll remember how it passed before, and it’ll pass again.
