Needing some encouragement

I am 39 + 5 today and I'm pretty sure I'm losing it. I've had minor complications throughout my pregnancy which lead my docs to tell me I'd probably deliver early so I never thought I'd make it this far, but now pregnancy is taking a toll on me. This week I'm just so tired and in pain! I have sciatica and GI issues. And yesterday, I started to get super emotional and just cried all night. I keep looking up symptoms in the hope that it means I'll go into labor soon.

Any advice for this very tired FTM?
