I often experience this - focus of it will vary but it's stomach churning, adrenaline going, feeling of overwhelm and brain cycling round the same negative thoughts. Sometimes I can sort of name it, identify the trigger and try to talk myself down from it/try to let it go.
So for example I might try to think to myself. I'm feeling anxious, that's ok. It's about the holiday we've booked and whether it will turn out to be a waste of money or whether we spent too much. It was a big amount of money, and we will enjoy it even if things go wrong because we have enjoyed all other similar holidays even though none were perfect.
But sometimes, as today, it's not so much anxiety as regret or intrusive thoughts about things which I feel I should have done better. Today it's work related (something I did in the week which is yet to be presented to peers, and am now fixated on what I could have done differently, how I 'failed' and how peers will judge me about it.)> It's not quite anxiety. I was anxious before the thing, but coped OK. Now it's persistently in my mind, and even if I focus on something else it's making me feel on edge even as I just cook lunch and not actively thinking about the thing. Like the physical feelings remain even if mentally I'm not conscious of it
Can you help me name this and think about how to accept it/let it go?
