paxil and xanax

Help!!!! I use to take Paxil for almost 10 years and went off of it a year ago in March 2009. I have started taking it again! My panic disorder has come back in full attack!!!! I have been on 20mg for 3 days and I am experiencing increased anxiety. It is becoming very frightening. Before I started taking Paxil I was taking xanax .50 4 times a day. Now since starting the paxil, I take the xanax and I am not getting the relief that I was getting before the Paxil. Could someone please confirm or deny these reactions that I am having. Also, I called my doctor today and since I have lost so much weight and I am having an extremely hard time eating, she has also prescibed 2.5mg of zyprexa to help with my appetite. After reading all of those side affects, I am not sure what to do. I am scared to death. I don't have bipolar or schizophrenia. I also have low blood pressure and that side affect concerns me. Could someone please help me! I am desparate!

The three days aren't enough to know if the Paxil is going to work the second time around.  It might not, it might, but it takes a few weeks for it to fully set in.  I kind of question the Zyprexa, though -- Paxil adds enough weight to most people!  But as for the Paxil kicking in, you still have more time to wait before knowing if it's lost it's bite for you.
