Why don't you check out Calmbirth or Hypnobirthing classes? There are other options than simply 'epi or not'.
No one is very good with pain, and there is pain in labour like it or not , but it is a different kind. Trust me.
If you can try to change your approach to pain and labour and not fear it too much you may not need feel the need for an epi at all.

I HATE needles so much I chose the pain over the needle in the back..and it wasn't that horrible after all
