I'm so bitter

I desperately want another baby. I have a stepson and a biological child. I love them both dearly but I want one more. The problem is we literally can not afford it. We are in one of the cheapest (yet highest rated by the state) daycares and still pay close to 9k a year for one child. No way we could afford another baby and pay 18k a year. We can't wait until our toddler is out of daycare either because of our ages (husband would be pushing 40 and me 38). Husband clearly stated he's not "starting over again" at 40 either. I'm so bitter that we work our asses off and still can't afford it. We both have very good jobs, but with the economy, there is no way. I jist want to curl into a ball and cry. I know I should be happy with the two boys we have, but I've always wanted two biological children. Two babies. I love my stepson dearly but I missed most of his childhood so it's not the same.
