Today, I had an argument with a friend over the phone, then as I was talking to her, My breathing starts to become heavy, I can't event complete a sentence without taking 4-5 breath.. then my hands starts tingling until it's completely numb and my heart is racing, and then I couldn't breath anymore and I was choked for a while. Was i under any heart attack or anything? or is it just due to the stress of the argument that my body is acting that way?
