I am still telling myself that no it's got to be something else like I it's my heart even tho I have been diagnosed with generalized anxiety disorder and have had all the tests to make sure it's not my heart. Apparently Maven is right about it being a symptom of anxiety I have been told that a few times I am always looking for assurence that it's not my heart....the thing is the physical symptoms like my heart beating loud and fast or it feels like it jumps in my chest and the chest pains makes me always second guess my docs diagnoses that maybe she's wrong and that it's something else. So I dwell on it and worry causing my own anxiety, if it wasn't for the physical symptoms I would be fine.
