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.
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!
