the guilt

I'm a little surprised at the amount of guilt i feel throughout this whole process. Ok, I'm a lot surprised. My hub is the same way. We aren't celebrating Fathers' Day, we're celebrating Foster Father's Day... It just feels weird to him and me too a little. Like when Lil Bit goes on his visits with his mom and dad: I don't get to go and for safety reasons, I can't even be the one who drops him off. So someone we don't know comes and picks him up, takes him to visit with his parents (whom we never met) and a visit supervisor (another person we don't know) and then he's brought back to our house. Not a word on how the vist goes. And I hate it. Every visit day I get anxious and then the guilt sets in... Who am I to be nervous about Lil Bit? This must be what his parents feel on a daily basis, he's living with people they've never met. Lil Bit's new case worker is coming to meet him this week (this is where I imagine them shaking hands and the caseworker introducing himself to Lil Bit) so I'm hoping to have some sort of information after that. I just want to have an idea of what is going on with his case. I've never done this before so I have no idea of what to expect and all the while I've got this sweet little man to worry over.
You see, half of my guilt is what if he stays with us forever and doesn't know his birth parents. The other half is what if he goes home? I will be crushed, but do I have the right to feel that way? I worry will his parents make sure he gets his medicine and will they figure out how he likes to be held? HELLO? His mom must be thinking the same things right now!
Aaah the guilt... someone make it stop, please?
