Yeah so many times anxiety can be part of something else.

I was treated for depression for years. Then I quit smoking and from the ashes rose my anxiety. In the midst of learning to deal with both depression and anxiety and wondering why I could suffer each very intensely and for sometimes short periods, like hours, came the diagnosis Borderline personality disorder.

Honestly, when I'm really anxious I tend to not be able to sit at the comuter long--gotta move!
