I just can't win

I really can't win... I had the talk with my boss since she is pregnant but now that she is starting to show and get the attention that goes with it she doesn't care anymore about openly talking about being pregnant in front of me. I mean she is always talking about how exhausted and tired she is and how she can't even stand for long periods of time... and of course my co-workers are non-stop talking about it and fawning over her and all in my face.
It isn't bad enough I am approaching my due date but hey while I am trying to deal with that let's throw this insult right in your face!! I mean I just don't want to get out of bed anymore. I just want to sleep and then when I do I have nightmares.
last night I had a nightmare that my sister in law who declared when she potty trains her first child she and my brother are going to have another kid... she barely made it through her first pregnancy but she doesn't care. She never ate right, never did anything right the entire time and she thinks she did and that she can lecture me about having children. If she wasn't in CA I think i would have slammed the door in her face or something!
My emotions are so in the toilet it isn't funny or fair anymore. I don't want to be around people anymore. I mean the other day my husband told me I had changed. The last three months I went from finding the good in people to just being negative and picking on people.  I mean do people think I am going to run around singing sunshine and rainbows with a fake smile on my face? I am not that type of person. I am hurt, angry and bitter at the world. I am not going to pretend otherwise.
Just wish I could stay in my house and not leave.
