Your husband is correct. 'what's the worst that could happen'? psychologist to myself ....... I understand that deep breathing can help, also using a brown paper bag over nose and mouth. I was instructed: sharp breath in through the mouth, count to 10, let out slowly through the nose, it might have been the other way round

; the idea being to practice regularly so that it becomes 2nd nature to stop anxiety surges.
At the same time, have a word for the brain to focus upon, i.e. "relax", "calm", sunshine .......

1 of my problems was of 'spoiling things for others'. Drummed into me from an early age.
