Add me to the group of crazies. Ive never been officially diagnosed, but after talking with many people who have, it sounds just like them. When I feel it coming on, its like a dark cloud that just descends over me. My heart starts to race, I get almost like tunnel vision and I have to remind myself to breathe. I start calling loved ones to make sure they are ok. Last one I had was really bad. DH was house sitting for his parents, 15 minutes away. It was almost midnight when it hit. I layed there thinking, it will go away, Im fine, just breathe through it. After what seemed like forever, and it not getting any better, I grabbed my phone and started this long winded text message. I guess by focusing on texting, it got my mind off of my AA and right about the time I was gonna hit send, I realized I was gonna be fine. Scared the living daylights out of me. Ive never had one that bad. I really thought i was dieing.
