getting close to birth.

Antwanette
I'm going to be 39 weeks tomorrow and I'm absolutely nervous about giving birth. At first I was okay with it and not worried knowing my support people are here for me. But lately I have been feeling distant from everyone; scared about becoming a mother; loss of appetite; more Braxton Hicks within an hour; nausea; and not to mention I have ADHD and can't take my medication. All this has become way more overwhelming. Does anyone have any tips to help or calming thoughts. 
Not to mention I'm 1 cm dilated, and my mother and father of my child dislike each other. Well my mother hates him and feels I need to choose between the two. I don't know what to do or who to talk to.1
