There are some great essential oils that can help you with this. Lavender and wild orange and also Do Terra has a blend for those feelings. Oils are safe and very effective. You should find a rep in your area or just go online. I use oils daily. Good luck!
Yes I deal with Anxiety on regular went to talk to talk about it because I felt like I was going insane lol. Not much you can do while pregnant though honestly. I just try to stay busy and keep my mind occupied. It helps for most part.
