Yes life is a chain of struggles, my experience anyway.

I read your thread and saw 'Vent' so did not respond initially, but I came back to check how you were today.

I don't know too much about the sensation you describe but I have read that some find it helpful to have something tactile to ground them when this happens. Some recommended things include a sharp flavour, chewing a piece of ginger or chilli, or rubbing a piece of fabric that is soothing to you, taking in the sensations of the texture.

I don't mean to patronise you, but I myself find touching fabric can be soothing and calming.
