I feel like I'm having a heart attack all the time and my Dr told me it's just anxiety and I'll be ok but I feel embarrassed and don't want to sound crazy. I have so may symptoms that I feel like ppl think I'm just making it up. All heart attack symptoms, numbness in left arm and leg, neausa, shortness of breath, dizzyness, trouble focusing my eyes, chills, and others. And all this 5 out of 7 days for a few months now. I also feel like I can't find a happy medium with things. As in I ether feel like I'm holding my breath or hyper ventilating, my I'm sbaking with excitement or sleepy. It can change in a second. I'm 26, in shape, 5 years ago had a sudden intolerance to caffeine, no panic until this summer and it's getting to be daily
