heart attack versus panic attack

How do you know the difference? I mean, they mimic eachother, but how do you know when you are in trouble? I try to tell myself, okay, this is panic again, but this little voice says, wait, maybe it really is a heart attack, you don't want to push it. How do you know???? My friend had anxiety and had a heart attack and I can't stop thinking that he was probably trying to brush it off as panic again. I have symptoms, chest pain, dizziness, shortness of breath, etc. Does a heart attack happen quick? Would it linger, could you move around, etc??

Im not sure. I often wonder about that too. BUT I have heard you WILL know if its a heart attack. Ive had so many sx for so many yrs, on and off. I try to tell myself that Im still here after 17 yrs of this ****. It all started w. heart attack sx. Ive been to hospital uncountable times. Hope you feel better soon!
