Delphyned,Lexapro can cause a rise in your anxiety at first but it was just temporary for me - I liked this drug but it pooped out quickly.
I also was on Cymbalta for quite a long time - at least 1 year but it also pooped out......... I have depression and anxiety so finding the right one is difficult. I am currently on Effexor XR @ 300mg every morning.
Good luck,
Kitt
