help!!!

So I am starting week 5 tomorrow and I feel a mixture of things. To begin with, I was told  by my pcp to immediately stop taking my celexa (ssri) when I got pregnant. Now my anxiety is showing up again. I wake up at night with my heart racing and feel that sick anxious feeling throughout the day. Also, I am nauseous in general now. It's so early in the pregnancy I want to know what might help with my anxiety and/ nausea. Is Dramamine ok? Any help would be appreciated.
