What Is The Best Procedure To Come Out Of Paxil?

I am trying to find the best way to quit taking Paxil. I have been on it for about 15 years. I was on 40 mg and when I told my doctor that it did not appear to be working any more she gave me a prescription for Celexa 20 mg, said I would probably have some withdrawal from the Paxil and sent me on my way. Within days I was in the emergency crying uncontrollably and barely able to function. The mental health care worker gave me a prescription for Quetiapine Fumarate 25 mg and told me to take one every morning and it should help with the symptoms. After nearly a week of hardly functioning and many hours spent contemplating the ceiling and a whole lot of nothing else I went back to the doctor where the solution was to only take it at night. I have not been to work in more than a week and am lucky to have a patient boss. I have not taken the Quetiapine or the Celexa in 3 days now. In desperation for answers I have since returned to my previous doctor in a neighbouring town. This is a doctor that I very much trust but is really to far away to see regularly. It is my intention to now wean myself off of the Paxil altogether and then re-access the need from there. I would like to be free of the drugs altogether and find a natural solution but I need to have some guidance as to the best procedure so that I can at least feel well enough to return to work while working thru this.
