B.K.
I was in your shoes once, and I know how confusing it all seems. But take it one step at a time and it's not such a big deal. I am including a link for an Illinois adoption agency that works with people across the country. I have friends who adopted through them and it was a great experience. I went through an agency as well, but mine only works in Illinois and Indiana. My older daughter was about 4 when I had a miscarriage and then couldn't have any more children. She was 9 when we adopted my younger daughter. It was meant to be for our family and I'm glad that it all worked out the way it did, although it was hard going through the sadness of miscarriage and infertility. Message me if you have any questions. I would check out the website and perhaps call a counselor to see what your first steps might be. Good luck to you!
