It sounds like a typical anxiety attack to me. An important thing to try to do is figure out what gives you the attack. This is going to require you to be honest with yourself, even if it's not what you want to think about. Another important thing to do is assess whether you are in immediate danger. If you are not, you may be able to talk yourself down from your high anxiety level.
Good luck.

Sibatyra,

try deep breathes when the attack starts to come on.
Also try to pay attention to how long the worst part of the attack lasts, typically 10 seconds. You can take anything for 10 seconds, you can do it! Knowing that you will be ok in just a couple of minutes will help keep the anxiety from manifesting.

Anxiety does cause the mind to be confused. When your body gets the high dosage of andrelayne the body goes into "fight or flight mode" which inturn shutsdown parts of the body that are not needed (digestive system, hair doesnt grow, the sophisticated portion of the brain(speech))

try not to worry, it is not going to kill you and there is no permanent damage to your body due to anxiety.
