Stinky,
If you believe you or a family member is having one,you should seek medical advice right away....Do not leave it...A nervous break down,can cause a stroke or heart attack...(if not physically healthy)...my auntie had one,left it too long and had a heart attack...I think you have gotten all the indications from the other posts on what the symtons are...I hope you or a family member are all right....
