Yes. It's the worst feeling in the world. I went through a period when I first started college where I would get them all the time, but it wasn't related to school. I'm not sure what triggered it though.

They would usually start with a feeling of unreality or almost like a dreamlike quality. It's just a sense that something Ian right or you feel a little separated from things. Then my heart would start racing and I would get the feeling like I couldn't catch my breath. It would keep getting worse and worse until my hands and face would start tingling and I would feel like I wa about to pass out.

The anxiety would just kind of feed on itself and the more you worried about, the worse it would get. I felt like I wasn't in control of my body and that's a really scary feeling, at least for me.

It was a lot worse when I first started getting them because I didn't know what it was or what was happening. I thought I was going crazy or that I was having a heart attack or something. You start thinking things like that, coupled with the feeling of not vein in control, and it just becomes a vicious cycle. You start worrying about getting them at certain times, like when you're in public and you feel like you have to hide it.

Eventually I had to learn breathing techniques and other ways of calming myself down. I would focus only on my breathing and just let it run it's course. After awhile, the breathing techniques start working and they wouldn't last quite as long. I stopped getting them all the time once I started feeling in control again. I stopped having them at all eventually. You get really good at identifying that feeling before you're about to have one. Again, I would just focus on my breathing and try to relax and realize that I was actually in control. Eventually even that stopped and I learned to cope and deal with my anxiety better.
