I'm having anxiety. I keep thinking something is wrong with me now and it maycause complications during my surgery.My chest is tight. Ive seen a cardiologist in the past and he said i have a strong heart but when i get anxiety i get episodes of tachycardia. Otherwise im a healthy 30 yr old. I was scared During my preop the nurse made me feelbetter then it started again. I have 100% trust in my ps I think I'm scared I have a preexisting condition that I'm not aware of lol. Am I losing it?
