I have been on paxil for years 40mg and was switched to Zoloft 25mg less than a month ago. I felt bad for the first week and a half and then I started go feel better. All of a sudden I feel horrible again. Constant anxiety!!! I was told by someone who was on Zoloft to "be careful" because it made her anxiety much worse. I'm constantly freaking out. I just want to be "normal". And responses will be greatly appreciated! I also take xanax .
