Aww hun, sorry you're feeling down. Your true friends will always be there for you, and the one's who are acting wierd probably just don't understand what you're going through. Being a Mummy will no doubt introduce you to loadsa new friends, who are more than happy to talk about babies and such stuff.
And if you're ever feeling lonely then you've always got your friends here on B&B who you can have a good old moan/natter with!
