9 months pregnant depression

Anyone get depression and anxiety really bad the last month of pregnancy? I have severe depression and anxiety disorders but this entire pregnancy I almost felt like I didn't have them anymore! I felt better than I have in years. I can't say that now... I'm 37 weeks and 5 days today and cried because I haven't gone into labor yet! I know it's still early but for some reason I'm so upset she's not here yet. I'm terrified to go overdue and need to be induced or a csection. Also this entire time I've been so confident in becoming a mom but now I'm questioning everything. Especially when it comes to breastfeeding! How am I going to know when to feed her or if I'm doing it right? I already feel like I'm never going to sleep just to make sure she's breathing all night. Should I be worried about getting postpartum depression or anxiety? Is it normal to feel more depression and anxiety before even given birth?
