In today's day and age, Maryam bint 'Imraan would be considered just another young girl pregnant out of wedlock. When the priests of Bani Isra'el kicked her out of her sanctuary due to her pregnancy, she was effectively rendered homeless. We would have written her off as another unfortunate statistic and pity her child as being unable to have a stable home or any kind of meaningful future.
Instead, Maryam became one of the most famous women in Islamic history. She defied the odds and defied the animosity of her society, and was able to raise a Prophet who changed the course of history.
Never give up on the hundreds and thousands of young, pregnant girls and single mothers. Never write them off as "hopeless" and their children as 'burdens' to this Ummah. Instead, think of them as one of the most powerful sources of hope for this Ummah: Those who, with strong emaan and the right tools, could raise a generation of Muslims who have overcome the odds with a strength that will help change this world for the better.
