Suggest Treatment For Heart Palpitations And Stress

My name is Staci and I just turned 45 in December. I have my period regularly and no signs of Menopause so far. I sometimes get heart palpitations off and on during PMS and Menstrual Cycle. I was told this was hormones. I am under an unusual amount of stress right now at work, and financially at home. I have OCD, anxiety, and high amounts of stress in my life. I am however, very productive and busy with work and family. I take 80 m of Prozac per day for the past 20 or so years- helps well with the OCD. I take up to 2 m Xanax at evening time for past 16 years, and Prilosec for acid re-flux. This week I started experiencing heart palpitations on a daily basis every half hour or so just sitting at work or on the go. I am PMSing but have never experienced this many palpitations before and so constant. Could this be stress along with PMS and hormones? or should I see a doctor? My BP is normal (low) and cholesterol normal (low) with no known health problems. I exercise 2 days per week and am very active. I am 5.1 177lbs. Can you give some input on this? I am guessing it is stress related- work is very stressful right now- more than usual, and with money being a worry at home it is very stressful! I can feel the stress in my body! But have to work to provide. What do you suggest? Thanks, Staci -I am sorry I just saw that this site requires that I pay money in order to get some advise. I cannot afford to pay as I am overdrawn in my account. Thank you anyway. Staci
