Yes that is all the symptom of anxiety. I went to drs. constantly back when i first was going through that. The doctors found absoulutley nothing wrong with me infact they said I was in tip top shape very healthy.
Right now I am reading a book that is helping me get back on track. Just this past weekend I had a real bad attack and since then have not been feeling right. So I'm doing relaxtion excercies and writing positive things down just really focusing on on what my set back is all about. Then turnign it all into positive thinking. Cognitive Therapy really helps it takes time an effort on our part but have to really want to do it.
Look it up online or go to your local library and get a book called
Anxiety& Panic Attacks their cause and cure
