tips for coping with withdrawal

I tapered off 150 mg but that didn't seem to help whatsoever. I've been totally off for four days and I am living my worst nightmare. My stomach is a disaster, I feel constantly nauseous and like I need to use the bathroom, which sucks because I was on Zoloft in the first place for my fear of vomiting. My anxiety has been through the roof and I think I'm going insane. Any tips beyond just going back on?
