I need a place to stay

Try enquiring in a youth hostel.

Is there a safe shelter there?

Be careful, if you do decide to leave, as someone has said, find a church willing to help. There is help out there, but be sure, the world that we live in, it's not safe. One good thing, you have a job, that's a start. Keep the job, you're going to need it. Most churches will help especially if they see that you are serious and trying to help yourself, by working. I am going to keep you in prayer.

Contact a local church and let them know, you will more than likely find a safe place to stay through them and also wont be to expensive. As a 19 girl unfortunately there are lots of sickos out there who might want to take advantage of your predictament.
