So I didnt list all the signs of a panic attack or all the feelings of them, their are many and it depends on the person. This is simply based on my experience of having them and from people I know that have had them or are diagnosed with anxiety have told me they experience. I am not a therapist or psychiatrist, I am just someone who has anxiety disorder(s). It could help someone to know signs of having a panic attack and help people to try to help someone having one. I've battled with anxiety for my whole life.
