Having to send daughter to residential facility two states away for mental health issues. My heart is broken

Please pray that God continues to give me strength and peace. I am a 35 yr. old single mother with two children. Ages 10 and 1. My mother suffered a massive stroke in 7/08. Since that time I have been living with her caring for her. She is now rehabbed enough for me to go back to work, however I can not find a job anywhere. I don't know what to do. We are on foodstamps and living on her disability, it is not enough. I have no one. I am scared, tired, lonley, sad and depressed. I am fighting this depression with all that I have, I know that God is the only one that can heal my broken hart. He can heal the lonliness and give me strength. I need help. Please God, open the door, make me see the light.
