In reply to MarkAstley:
No resources as such, but looking into the process of being anxious, high state of arousal - raised heart rate - fight or flight state - raised adrenaline levels, anxious thoughts/thoughts which one wouldn't agree would be true if somebody else said them 'people are thinking X about me', and that kind of thing might be helpful. The lady I saw commented that I was among the most anxious people she'd seen, and for me a big breakthrough came when I realised that the outside world stayed the same whether I was anxious or not, so I thought 'Sod it, I'll be anxious if that's how I'm going to be', and it progressively reduced the more I did (there can be a feedback loop created, where one avoids situations because 'they cause anxiety'). There's a process called graduated exposure, too, where one can (for example ) catch a bus progressively further towards overcoming that thing being something one is anxious about. I think becoming more aware of the process of being anxious itself, towards gaining a certain detachment from the process is what ultimately helped.
I hope that's of some vague help, I didn't really use online resources at the time I was going through it, but I went to anxiety management classes for a short while. I hope things pick up for them.
Edit: Depending on your relationship with them, and their personalities, having a goal to recover for might be helpful, I had not letting certain teenage mistakes 'spoil my lifepath' towards returning my mind to being functional again.
