I do not have a history of anxiety. I am 31 years old and over the past few months I have had 5 sudden cases of anxiety. They don't seem to be brought on by anything. It comes with a taste and smell. At times my head shakes slightly to the left and i often have headaches based in my temples. I used to drink coffee but quit about two months ago. I do still have a diet soda once to twice a day that is caffeinated. I am in the process of being evaluated but no one is telling me much. I am curious what the possibilities could be. I realize that you can not diagnose but some ideas would be helpful.

Thank you,
Lydia
