Hmm, some of that sounds like it's describing Panic Disorder, which IIRC isn't a diagnosis you have? (All that meta-stuff like "panicking about the possibility of having a panic attack" is a real vicious-circle of a state to be in, for sure, but it isn't the ONLY way to have panic attacks.)

So yes: take the stuff that's useful to you, and let the rest fall. <3
