Giving my baby up

Just turned 20. 33 weeks preg . Unexpectedly homeless. Have been trying to get a job for over a year. County won't help me out financially or help me with housing besides $130/month. Beyond depressed and having suicidal thoughts. As much as I want my baby so bad I feel like I have no choice to give him up for last minute adoption I have no family members to watch or keep him temporarily and no means to care for him im a failure of a person. I've done all I can to get help and try to find a solution and I'm at a dead end...does anyone know of any creditable adoption centers or programs? Something like that...im in Los Angeles
