Transitioning from Paxil CR

Is there an effective SSRI that can be taken while withdrawing from Paxil CR? I've been on Paxil CR for only 7 months. It was prescribed by my psychopharmacologist as a replacement for high doses of Lexapro. Dosing down on Lexapro and going up to 62.5 mg  Paxil CR was relatively easy. However neither medication has treated my depression adequately. I've been travelling the road of Prozac, Zoloft,Welbutrin,Celexa plus Xanax for at least 6-7 years but my depression only gets moderately better. I started before menopause and am now past that point and I feel worse now that I did before I started treatment. I've had panic attacks on both Lexapro and Paxil and even taking Xanax XR doesn't prevent the panic attacks. Once my serotonin dips, it requires some kind of anti-depressant to stop the attacks. I can't concentrate, have severe lethargy, all over body weakness and can't work - but I'm not sick enough to get disability. AND I don't want to be disabled. I used to have a management position with a six figure salary and now I'm barely functional. I'm too weak, too tired and too angry to care much about anything.

I've read many posts about withdrawing from Paxil and Paxil CR, so I'm less interested in the horror stories and would be very grateful to hear any success stories. Thanks.
