Severe anxiety

I was on Zoloft and 1mg of Ativan/day before I was pregnant. As soon as I got my BFP a I stopped taking my Ativan on my own accord and just kept taking my Zoloft. I am now 17 weeks and my anxiety is so severe I am barely functioning. I can barely work, drive, go grocery shopping ect. Without having dibilitating panic attacks. Just wondering if anyone has been in the same boat and what has worked for them? Thanks!
