I've been having panic attacks from December and recently they are more frequent especially when travelling to work in the train. It's come to a point whereby I have to get off random stations at times when the train becomes even a tiny bit crowded.Me and husband booked a trip to Paris during the Easter weekend and planning to take the Eurostar. I do not want to spoil the trip for him by cancelling it...but the thought of going into a tunnel makes me physically sick..I've been commuting for ages and never had any issues nut now everyday seems like a battle..has anyone experienced this before?
