When I'm having anxiety attacks, I can generally work myself through the feelings associated therewith, but when I get into a full blown panic attack, I can't ... Not sure if that makes sense or not, but I'm aware when my anxiety's growing and if I don't start doing things to take the edge off of it, then I find myself falling into a full blown panic attack and there's no taking the edge off of that until it's run its course!
Simplified: I can reason with my anxiety ... I cannot reason with my panic!
