Where do orphans go after they turn 18?

@SW-User I was hoping that somebody would tell me that there are some programs for 18+ previously orphans. And apparently there are some, so they aren't all alone.

@Dan193 A lot of the time they are pushed to get a GED, go into the military or get a job.
And most of the time thats hard to do when you have nothing.
So a lot of the time they sometimes end up homeless on the streets

@SW-User Even though I don't know any of them personally, it breaks my heart that they're stuck in such circumstances. I wish I could help them.
