Help With Anxiety

I have depression and anxiety among with a few other things that I was being treated with Zoloft and Trazadone. I stopped taking them when I found out I was pregnant. I have an appointment Wednesday to talk to my ob about what I'm able to take, but as of now my anxiety is really high. I've been dealing with the depression, kind of. But I woke up this morning and my heart is racing and I can't stop thoughts running through my head. I was just wondering if anyone has any tips how to calm down without taking medicine ?
