Depressed, I don't want to be alone!

I'll be 36 weeks on Thursday and I'm scared I'll be alone on the day my daughters born. Her father is in another state working. 3 hours away and he doesn't know when he's actually coming back maybe this week or next week but I'm scared he won't be here. That's all I've been worried about since he left a week ago, I try to stay as positive as I can but it's so hard thinking he won't be there and I know it'll hurt him the most. This is so depressing, I can't 😞
