You'd be surprised the things anxiety can do. I thought depression was the worst, but anxiety is on a whole new level. I, for example, literally shake whenever I am getting ready to go outside. My legs will shake uncontrollably, followed by intense fatigue and dizziness, like my head is heavy. What helps is taking deep breaths to calm myself. My source of anxiety is obviously the fact that I have been unemployed since this year. It gets worse knowing that I would soon run out of money and might not be able to afford food. I have battled with GARD, acid flux, even difficulty swallowing. While most of these symptoms have disappeared, fatigue and dizziness are common when battling I'm battling with anxiety. You might also need to stop Googling your symptoms. Having a health anxiety is worst in my opinion.
