30 weeks and 5 days pregnant with anxiety

Well I'm 30 weeks and 5 days and my dr has decided to book me for a c section. I have an anterior placenta and also suffer with anxiety. Her main concern is that I'll stress myself out and the baby. Usually my anxiety attacks flares are accompanied by an out break of hives ( urticaria) and heart palpitations, it makes it really difficult for me to breathe. She says it just isn't worth taking the risk. 
Any other ladies out there that suffer with anxiety and how r u dealing with it?
