Venlafaxine
"Venlafaxine didn't work well for me, although I was no longer anxious, I did feel like I was a zombie. 

My message to anyone trawling the internet for answers & hope.  YOU WILL GET BETTER!

It may take time and trial/ error with your treatments, but every human being is different so if one treatment worked for someone and not you, then there are a whole host of other treatments & combinations. 

Talk to people whether family, friends, support groups, online forums.  Go to your doctor or consultant and take all the help you can.  If you are not happy with your treatment, ask for a different healthcare professional. 

As I write, I am in recovery on Sertraline.  I have agorophobia, but am starting to get back to a somewhat normal life."
