I am very sorry to hear about your grandparents and hope they get better soon.

If you are not in your home with your mom - where are you staying. Are you in a safe place ? are there other relatives that can take you in ? Are you a member of a church that can help ?

It sounds like you have a court date for something that has happened and you are concerned about having to serve some time - do you have a lawyer ? Can you speak with your lawyer about getting assistance with a place to live - attorneys usually have lots of contacts and might be able to help. As well as help you with whatever legal trouble has happened.

take care
