Well done for getting the psych referral sorted - the difference I found was the my pdoc could diagnose combinations of meds that my GP couldn’t. I suffer from depression and social anxiety and could very easily have written that post from you. I’m naturally an extrovert but it seems like a switch goes off in my head and I can’t cope with people any more.
Edit: of course that meant seeing a psychiatrist. A psychologist deals more with talking therapies whereas a psychiatrist deals with medication
