mummyanxious, neither am I!!!!
I hate the gym, I hate exercise, I eat a load of junk, am the wrong side of 40, have GAD/panic and yet my blood pressure is low.
Things don't always add up, nor have to, they just are, it doesn't mean anything sinister is going on.
I can't help but think that if you do 'know the symptoms of anxiety' you would know that many of yours are anxiety symptoms! Shortness of breath, weakness, chest pains/tightness, fatigue, ringing in the ears, etc. x
