Need advice: struggling to become a SAHM or a working mom

Im 5mth pregnant with my first child. My husband works and I don't. I get so bored at home that I become very depressed because I miss being independent and my family lives far away and I do not have friends where I live.

I have a degree and I'm 28. My husband is 41 and pretty settled in his career. We dont struggle with money but I want to make my own money and just be able save up my own money and what not.

I miss the working life and obviously I want to be able to alway provide for my baby. I want to go to work right away when the baby is born but I feel guilty for wanting to leave my baby... I just don't want to be home all day by myself ( husband works all day and night) I just dont know what to do...
