girls, help me!!!

I'm absolutely miserable & struggling!
I've battled with addiction and depression for the past 5 years. I've managed to get clean & off all medications to ensure a safe pregnancy. I'm currently 39 weeks & 1 day but I've been really really struggling the past 2 weeks..with my depression & having cravings..
I really don't know how much longer I can just sit around waiting for my baby and trying to keep my mental state healthy... I can't stand the anxiety, the unknown, the waiting... I'm really wishing my baby was here because I know that will keep me on the right track! 
Just needed to vent. Any advice will be helpful!
Due : 9/27
Edit:: thank you ladies for the advice! I told my doc I'm very depressed she just told me it's normal at this time in the pregnancy.. But  I'm honestly so scared to tell my doctors the whole truth about having cravings and really struggling because I fear they might contact CPS and try to take my baby bc they could think I'm mentally unfit or even put my child in danger :(
