I have come to the end of my sixth week on lexapro. 10mg the entire time. I have not had one ioda of relief from the severe depression and extreme anxiety I started taking it for. Is it time to move on? My psychiatrist is clear that she thinks it is not going to work and wants me to start tapering down. I just wanted it to work so bad. Could it still show it's head for the first time this far into taking it?
