Advice for staying calm about labor

I’m a FTM and it was a long journey for me to get pregnant. I think for so long I was convinced it wouldn’t happen for me that some days it still seems like it’s not real. Labor is now 5 weeks away if the baby comes on time and I am starting to freak out. I am planning on an epidural but I just feel so scared of it all. Any advice on how to stay calm?
