I'm going to describe how my panic attacks go see if anyone has similar or completely different. So first the build up is shortness of breath, lightheadedness, sweating and random little pains. This is what sets my mind off, I'll try to chill out in many cases now I can just chill and stop it but in the big panic attacks I have I find it hard so all of a sudden I'll get a strange shock run up my body this is what sets off my huge panic attacks cos I have no idea what it is. My heart starts pounding, I feel sick and sometimes do vomit, shaking, sweating, chills and dizziness which makes me feel like I'm going to faint! But I've noticed it's always the shock feeling that makes me think something is terribly wrong and this is what sets all the worse symptoms off! I did have a big one today unfortunately but I didn't panic as much as I used too because I knew what it was so I'm improving, I also used to have them at least twice a week, this is the first I've had in almost 3 weeks.
