I notice this everywhere now. Everyone has 'social anxiety' that seems to prevent them living a normal life. Being shy from time to time is normal and happens to everyone at some point! Seems to me that labelling yourself as 'anxious' rather than just shy is somehow reinforcing the issue, and gives you a reason to not try to overcome it because it gives it a medicalised label. They are called social 'skills' for a reason - they are skills that can be learned and need to be practised.
And yes I know some people have genuine anxiety issues, but people seem to reach for the social anxiety label automatically and it really grinds my gears! Or AIBU?
