Hi OP- I felt exactly the same as you re being petrified of forceps!
I knew the chances of me needing one were low as only a small % of women need them in the end.
But I just felt that knowing my luck I'd end up with forceps anyway!
I didn't believe that anything I wrote on my birthplan would be taken any notice of either.
So I took matters into my own hands & succesfully got an ELCS for maternal request. It was absolutely the right decision for me, baby was perfectly OK & I had a straightforward recovery.
So many people, mainly midwives, just told me to go with the flow, accept whatever would happen etc but I felt so much better once the ELCS was booked in & I could enjoy the rest of my pregnancy.
I wasn't particularly reassured by my midwives telling me that they/doctors would do "whatever it takes" to get the baby out 
Not sure what point I'm trying to make but ultimately it's down to you what you are comfortable with & willing to accept.
For every poster on here who says they had forceps & it was fine, there'll be another poster who had a horrendous experience with them.
Good luck & try to enjoy the rest of your pregnancy.
