Okay, please don't take this the wrong way, but I think you may have created a "Girl Who Cried Wolf" situation for yourself.
You post here almost daily, and your posts are usually complaints about people not pampering you enough during your pregnancy, feeling jealous of all the attention celebrity pregnancies get, people not making enough of a fuss over you, you being jealous of the attention being paid to your brother and sister in-law's new baby (because you feel like nobody is paying any attention to you), worrying about people not wanting to come to your baby shower, feeling like your family and your boyfriend aren't as excited about your pregnancy as they are supposed to be, feeling like people aren't treating you as "fragilely" as they should because you are pregnant, and feeling hurt because your boyfriend/mother/friends/whoever are accusing you of whining all the time and trying to milk your pregnancy for the attention.
So maybe it's time to take a step back and really think about what's going on. Maybe you HAVE really been complaining to everybody too much, and they are sick of hearing it. And now that you are really starting to feel tired toward the end of your pregnancy and could really use some extra help, nobody is offering, because they just think "Same S***, Different Day."
I understand, as do most of the mothers here, what it's like to feel lousy during pregnancy. But nobody likes a complainer. There is nothing wrong with lying and saying "I feel fine" when someone asks "How are you?" when you're feeling horrible. Perhaps your family and your boyfriend are just worn out from hearing constant complaints, and as such, they won't be likely to respond sympathetically when you are feeling REALLY terrible and could use their help and support, even if it's just making dinner once in a while.
Just a thought.
