I went to urgent care early last month for the heart palpitations I was having after I had two panic attacks. They did an EKG. It came back good and the doctor said it was anxiety and stress. They gave me a low dosage of Xanax (which thankfully I haven't had to take). The heart palpitations were going away. At least I thought so. I just don't want to slip back into a pattern of worrying. I'm so over this.
