Pregnant and anxiety--need suggestions

Hi! I am currently 4 weeks pregnant and have such bad axiety. I've had it my whole life and used to be on Prozac until I weaned off about a year ago when ttc. My anxiety just seems to be worse lately. I'm already on metformin for pcos and Labetelol for high BP and really don't want to be on any more meds but I am miserable. I feel wired and shaky all the time, I can't imagine 9 months of feeling like I've drank 100 cups of coffee and so wired. Has anyone else had this issue, are you on meds for it? What natural remedies have helped calm anxiety?
