In Young Life, we have the privilege of extending Jesus Christ’s love to kids as they are, where they are. For high school and middle school girls who are expecting or are raising a child on their own, that love takes the form of a program called YoungLives.
Treating each mom and her child or children with unconditional love and respect, YoungLives offers teen moms relief from the isolation and struggle of their daily lives and hope for the future. YoungLives mentors provide friendship, parenting advice and help meeting the practical demands of raising a child. At YoungLives club and camp, moms get to socialize and have fun while their babies get the best possible care.
Young Life is just one of many places for teens to turn, regardless of what's up (or down) in their lives. I don't know about where you live, but around here there are a number of churches that do a great job of accepting and helping people of all ages regardless of their past, or their present circumstances. Keep looking until you find them. They want to help you.
Update: I should mention that you don't have to be Christian to get help from Young Life, or from most other Christian groups that I know about.
