Second time to be mom and terrified of giving birth

Hello ladies!!

I have been reading some posts about being afraid of giving birth for the first time, however i haven't found much about being terrified the second time around...

Im 20 w pregnant and I am having nightmares-panic attacks here and there thinking about it,the length of the process,the pain,the freaking pain!!the hospital (not a big fan) and the epidural that didn't work much (went for a walk once i got it.. anyone else??)

In my case reading about this doesn't help much.I was very calm the first time as i wasn't sure what yo expect, however this second round...any advice will be more than welcome!

Thank you
