Need to find out what was going on in that group home to bring her to that state. Most kids don’t exhibit that kind of angst until their Goth period, 16-17.
My brother was in group homes for several years. He had a housemate run out and kill himself after a staff member “dropped him a level” for a minor mistake. The boy lived in fear of dropping levels. One punishment was sitting with your elbows on the table for 30 minute periods. It can dehumanize the residents and lead them to hopelessness.
I could go on and on about the completed legal yet harsh conditions in group homes.
