Zyprexa withdrawal, how long will it last?

I was on Zyprexa for 2 months and noticed increased anxiety so I quit taking it. My doctor acted like this was fine because I wasn't on it that long. About a week after I stopped taking it and took 3 days of Rexulti, I started having severe waves of panic attacks and bad stomach issues I had no control over sometimes for 24 hour or longer. It's been about a month and the symptoms are coming and going more frequently. Please tell me that means its almost over. I haven't been able to work or do anything with my kids really. My doctor doesn't think I'm having withdrawals but I think she's wrong.
