No wonder you feel the way you do with what you have said, I get a very negative vibe from it all.

You need to forget about the negatives and focus on all the positives, I know this can be hard if everyone in negative around you. But if you just focus on the negatives all the time, you will only see the negatives. It's just my opinion but you have to focus on all that is good about YOUR pregnancy and not compare it to anyone else especially your sister. Everyone is different, and you will get out of it what you put in and what your feelings are towards it. Hopefully this makes some sense. Try and hang around people that are positive about the birth experience also, this may help- and even if you try and read positive posts on BB.

goodluck
