I have just had this problem recently were I just feel like I’m gonna drop dead. I get a headache I think I have an aneurysm, I get a chest pain or a heart palpitation, I think I’m going into cardiac arrest. I check my pulse 10x a day. I have been to a neurologist and had an MRI done and have been told there is nothing abnormal. I work at a doctors office and have had my blood pressure taken and it’s is book perfect, my heart rate, book perfect. But I still get into this cycle that something is wrong. How do I cope? How do I get myself out of this funk, I have days that go buy and I’m fine, and then I’ll get a headache and I get stuck in this spiral again…I just wanna feel normal without feeling like everyday is my last day…
