I have the EXACT same thing as you. Took a month off school because I couldn't figure out where this racing heart and shortness of breath was coming from!

Zoloft and anxiety meds personally didn't work well for me. They may be different for you, but as long as my heart rate is ok I don't mind the anxiety as much. I'm taking beta blockers now, they lower my anxiety, heartrate, and blood pressure, and I feel amazing with no side effects. I'm taking propranolol.

one more question about the propranolol...how long did it take before you were feeling the effects of it?
