Anxiety/Mood Swings

Is there anything you can take (supplements) or drink (herbal tea) during pregnancy that is safe? My last doctor told me I could drink a certain tea that was safe for pregnant women but when I had to switch due to insurance change at my husbands job, the new doctor is telling me no. My mood swings are absolutely terrible and so are my nerves. I can’t hardly handle anything without breaking down and crying in the floor and I’m over it and sure my husband is ready to leave lol. The man deserves a trophy for handling me so well. I just hate feeling like a nut case!!
