stressing right out! :-( really dont no what to do!

i was excited for my baby boy coming.. but for the past few weeks i cant get labour out of my head im tearing up every half an hour at the thoughtd of it and im not even excited for my we man to come.. im debating weither i made the right choise!:( i would never give up on my we man and hell be more than looked after when he gets here and ill love him with every bone in my body but thats only when hes here ! at the minute im in full panic over labour! im terrible with pain and i hate the fact of lying with my legs open for everybody (well not everyone but it seems like everyone)! i dont have a partner ( or baby daddy around) to bring in to labour with me... ( only my.mum) and i really dont want her to be their but i dont want to.do it alone :(
