I'm always nervous

Hi everyone. We just started fostering 6 weeks ago a 3 week old. Our little man is growing so big and everyone is getting so attached., I constantly say we are caring for him until his mom and dad can care for him. But honestly I want to adopt him if we can. But it doesn't really look like that will happen. We are so in the dark on everything. I have no idea of when the court dates are and I just feel like the social worker is making decisions daily and we find out with phone calls from other people. I am so sad today because we got a call that another group who helps with parenting skills is going to be helping once a week. Again out of the blue. We did this so we can adopt one day it may not be this little man but it will hurt so much when we have to give him back. I also work with an agency so they are a resource but I still feel so alone. I think I need a support group to talk to others like me. I just asked today I hope there is one. I have never cared for an infant and I LOVE IT! I can't get enough of his arms around me. So I guess how I need to know how do you all do it? How do you deal with the fact that one day this little person you card so much for may go to another set of parents? :( Diane
