The anxiety attacks would be helped with a mixture of beta-blockers and anxiety training.
Your GP would be able to get you the one and point you in the direction of the other.
I used to get them quite a lot but was free from them for a very long time but recently I’ve found them creeping up on me. When a panic attack gets me I try to lie down and not think about the anxiety (which is much more difficult than it sounds, making an effort not to do something often leads to it happening).
The anxiety will not kill you. It feels really frightening though and when you encounter a cluster of them it can be very disruptive and frustrating. Last summer my mum had one on the buses home and her real concern was throwing up in public and making a fool of herself. One effect of the anxiety is a tightening of the throat and the need to gulp and that can intensify the anxiety because it feels like it’s difficult to breath or vomiting might happen. The first time it happened to me it was in a car. I got the driver to stop. Got out and then slid down onto the pavement. I was surrounded by people all offering help. Most concerned that it was a heart attack. If you don’t know what is happening it’s very very frightening and tense.
Knowing that it happens and what it feels like and knowing you aren’t going to die or are going mad is the first step to conquering it.
