Feeling a bit anxious

Is there other people on this space that have had times they feel anxious 

At a training day, its in the city 

I only vaguely know one person and most of the content isnt really practical for me. 

I struggle to sit and listen in these kind of things and I need to move around a lot and If I cant do that I just sit there and think about how I am so uncomfortable and not taking anything in 

When theres group things I havent listened all day even when I have tried to so I have nothing to add. 

I realised I needed space so I have gone to this like reserve park thing to reset 

I really find these days hard
