Foster care isn't as bad as all the people say and our caseworker in my state are wonderful. They give me their personal cell phone numbers and come to our foster kids birthday parties and even buy them gifts out of their own pockets.
Call your local agency and ask for a foster care specialist. They will help you with financial stuff and doctors visits and alot of things. And we have a place called independent living when they age out of foster care to teach them how to live on their own. it also helps with prom dresses , graduation things like this.
