I stopped having palpitations for such a long time, but over the last week or so, they have come back and are really freaking me out, i am quite sure it is the panic but part of me keeps slipping back thinking i am going to have a heart attack or something. Also the dizziness i was experiencing has come back again after not having it for a couple of weeks, could this just be panic also?? My mind just seems to be thinking of all the negative things and none of the positive. It is really getting me down.
