There is nothing wrong with how you are feeling. You are starting over after 9 years and there is a lot that you will have to acquire - genuine needs not just stuff. However, you are in a tough spot, being that you work with so few people and don't have a close circle of friends at this time to organize a shower/celebration. It was 15 years for me from my last child to my previous pregnancy and had I not been blessed with being a teacher in a school that thrills for the party excuse, I would have been in the same boat you are in now.
I haven't heard a word this time around and didn't expect to, especially since we are having another girl. I am contemplating doing what has been suggested here on the board previously - throwing a welcoming party of sorts for friends and family to come meet the baby, have some cake or maybe even BBQ - since DH is really into cooking out - just to celebrate our last baby. I don't care if anyone brings anything, I just want to celebrate this baby and have something for her baby book so she will know she was special too. So that might be something you would want to consider. If you know ahead, you could plan it for when your family would probably be coming to see baby anyway and just invite the friends too while family would be in town.
Also, don't feel bad about venting here; we've all done it about some issue or another. That's what we're here for.
