I am a little bit on an anxious person and this has definitely got worse since perimenopause. Yesterday dh and I went into central London to see a show and see the Christmas lights. I am very much a country girl and hate trains, especially the underground while dh works in London so is very confident and forgets I don't always know where to go. It was crazy busy and we got separated in crowds a couple of times, had people push between us at ticket barriers etc. So I was pretty heightened the whole time. On the train home I was following dh through the carriages to find seat and the door closed between us. It wouldn't open and I felt trapped. I kept pushing the button and it wouldn't open. I had a panic attack and everyone just stared at me. Dh by now realised I wasn't behind him and came back for me but the guard had to get the door open. My issue is that I still feel panicking feeling this morning. Obviously much reduced but it's still there in the background. I keep getting waves of that fluttering feeling, lightheaded and sick. Any tips to try and calm my nervous system so I can get on with my day?
