Please tell me someone out there has had this feeling. The last two days I was fine and half way thru the day BOOM horrific headache, lose of sight and having to go to the bathroom. I have been thru the attacking anxiety and depression tapes. I have read both of Lucinda's books about 20 times. I have learned to control (almost all of the time) the panic attacks. I can't tell if I'm having a (silent) panic attack or if something else is wrong. Anyone?
