I suffered with a mild one yesterday (Wednesday) whilst on the coach with my boyfriend travelling to London, 4hour+ journey. I was fine for quite a while then I had to close the curtain *** outside bothered me, I started feeling anxity in my stomach and it build up and hit my heart and the pain was horrible, it isn't a type of pain that would hurt you nesserssery but it grips your heart quite badly. In the end I had to go to the bathroom to breath, horrible little white box at the back, I went there twice, when I got back, I put my hood around my head and put my boyfriends headphones in and tried to fall asleep, I was okay for about an hour then I managed to keep myself calm until the coach stopped, had to be in the bathroom for 20 minutes, take some immodium (helps you not go the bathroom) and I felt sick a good chunk of the day, with a lump in my throat and any disgusting sight or sound setting me off (I can't stand people who snort, cough with flem sounds and anything disgusting on streets) I can usual not care and forget but when I already feel ill.... well..
Anyhow, I enjoyed the day eventually, and I had no problems on the 4 hour+ trip home AT ALL. I eventually got my stomach to accept some food at 4pm (we set out at 5am, got to London 12pm). We left at 7pm. I'm busy until Sunday
I'm not looking forward to it because I tend to have a tiredness thing where one-two days of excitement and action, knocks me for down for about a day-3.
The very mild panic attack, altho I don't think I got to the top, I managed to control it, lasted over 2 hours.
