I had a really bad panic attack today, I went to watch the rugby which was at a stadium with over 80,000 people. Since ice had this "anxiety" I haven't socialised much. And it got my heart racing so much. My legs felt weak. I felt like I was going to pass out, my ears starting ringing and my chest just felt like it was going to burst it was so tight! This was about 8hours ago... But my chest still feels really awfully tight and short for breath. Can you get after effects from attacks?
