One can adopt wit no $$ from the public system (true you have to have some form of support, but if you didnt, you should think twice (maybe more than twice about parenting in that situation anyway). Not all of the children in the public system have disabilities and emotional problems, and most states allow adoption by older age, single parents, same sex, inter racial, interfaith, etc.
Having a perspective that is focused on sharing whzt you have to offer with a child vs finding a child that fits your ideal makes that process a bit more tolerable. But hey, you cannot predict what a birthchild's strengths and difficulties will be. No public adoption is not for everyone, and you do face certain risks, such as not being able to finalize an adoption with a child you've fallen in love with, which I think can be worse than adopting a child with emotional and or other difficulties.
So sorry for bringing this up constantly. Im like a dog with a bone on this issue. I hope not to have offended. I too desperately would like to get pg and give birth to a bio child.
