I have gone to hospital & my primary doc. At hospital got ekg bloodwork & xrays. Said all was well. My primary listened to heart and said based off what they did and he heard nothing was concerning to him. Even with this i still have heart attack fear. Due to my thoughts that what happened to my mom will happen to me. In not even 20 yet. No previous heart issues nor do i smoke or drink. I try to tell myself all is well and thst im young but i still panic. i was wondering if anyone knew way of changing thought process or at least controlling panic better?
