My gran is moving back in with her ex-husband, and she is kicking me to the curb by selling the house. What can I do? Please help.

Are you at an age where you can get a job and accommodation on your own, and fen for yourself? Maybe its time.

"kicking to the curb" is a nasty description. I bet it isn't that bad, and could be just suggested you move out?

What about your parents? Did they not want you either? If you are at an age where you can get a job, do that and offer to rent your grandmothers house from her.

You forgot to tell us how old you are. If you are 18+ and in the US, you are on your own. Other countries have a lower age.
