Stressed about giving birth??

I'm currently 23+4 and a teen FTM and thinking more and more about having to give birth..I'm scared about how painful it will be and if I'll tear, and how painful it'll be after. I heard it's a struggle to just use the bathroom. I'm also worrying about not having a female I know in the room to help me, only my SO. I'm worried about something going wrong with the epidural, I've heard sometimes it feels like it doesn't work :( any advice?
