Anxious

I am really excited about fostering, but I also feel that I'm setting myself up for disappointment. I have read everything I can find on fostering, and a lot of it isn't good. It's sad. Parents who want to adopt their foster baby have to give them back to their birth parents, foster children who upset the family, agencies that are impossible to deal with. Are there any good stories? I know we will deal with the same problems, but I really feel at peace with our decision. I go back and forth between feeling excitement and feeling scared. Even with feeling scared, I still feel at peace. I hate the waiting...classes won't start until August, then October at the soonest is when we are looking at a placement (if there is a match for us). It really isn't that long of a wait, technically.
