I used to have quite bad social anxiety and fear of crowded places so much so I couldn't cope on a crowded bus without freaking out. Its calmed down a lot over the last few years but I still can't cope around large crowds.
I have just been "invited" to the work Christmas party where there will be over a hundred people. I have essentially been told I have to go. I don't know what to do I have had panic attacks in crowded rooms. Last time we had a work do I didn't go and was pretty much told its not good enough.
