Matthew since this has come back have you read any of the other posts or tried breathing into a paper bag or do any of the breathing exercises?

It's hard to believe that you are dying when you are so upset. Being upset proves that you aren't dying.

You need to take control of this no matter how freightened you are because no one else can do this for you. You have to do it. See if you can remember how you've handled tough times before and try it for this too.

Make sure that you are drinking a lot of water so that you don't get dehydrated and feel worse. Also you need to keep your strength up so eat well.

It might help to take a walk or go for a swim.

Will you please let me know if you get in earlier to see your pulmonologist?
