Hi I am a 48 yr old femalel, 5'6", 117 pounds - i'm in excellent health - i have a resting heart rate of 47-50. Due to many family matters (i.e. illnesses, caring for family members, etc.) I have been suffering from anxiety for the past several months - unable to sleep, panic attacks, etc. I am hesitant to share this with my doctor - I have previously taken xanax (one half of the smallest dose), but am afraid to now because of my low heart rate and blood pressure (approx. 100/80) - i exercise almost daily - is there anything else i can take for anxiety?
