Recently diagnosed

A close member of my family has recently been diagnosed with cancer.

She is refusing to let us know anything about it, is shutting us out completely. We are aware that she has hospital appointments that she has been missing or has walked out of. She has blocked us from talking to her doctor and we are at our wits end.

She says that she wants to be in control but it is so obvious that she isn't as she isnow down to 5 stone 12pounds.

One minute she is telling us one thing the next she is contradicting herself and telling us something completly different.

She lied about attending for a biopsy so as she could go on her own. She had the biopsy without any anaesthetic but told the hospital staff that she had people waiting for er in the car park. She left the hospital and proceeded to drive home when she crashed the car as she was in so much pain. How do we get to let us in?
