KitKat: Just a thought, when did you stop taking the Paxil? Did you stop one day and then immediately go into taking the Zoloft? It could be possible that you are having some withdrawal symptoms from the Paxil and that is what is affecting you right now. However, it does sound like a good idea to check in with a doctor. I know I get all nervous when I have to start a new med because we never really know how our body is going to react.
Good luck.
