Anxiety is the default emotion. You feel it when there are not enough other emotions in your life. Want to get rid of anxiety? Make sure you get all those other emotions. Go to a museum, read a (non-technical) book, go to a theater, meet some old friends, listen to music. If that's not helping, go see a doctor, because this is curable and there is no reason for you to have to go through this. We have the technology.
