I Have Been Taking Effexor Xr For Years.. If I

I have been taking Effexor xr for years.. If I forget ONE DAY to take a pill.. that next morning... I AM A MESS... I hear swishing in my head.. dizziness so severe that I've bruised my whole side from falling into a wall... I tried several times to be weaned off... CANT DO IT.. HAVE TO GO TO WORK... cant work with these side effects from withdrawal... for years.. my dr..and pharmacist both basically told me Im nuts for thinking ONE DAY without pill can be so severe... BUT NOW BOTH DR AND PHARMACIST ARE RELATING TO ME...
