My sister is appearing to become increasingly stressed. I am not sure what is wrong but she quit her job a while ago and seems to have gone from exercise queen to house slob. She doesn't answer the phone. If I show up, she will answer the door after repeated knocks. The flat is a mess. She can converse animatedly about politics, but suggest a shower and she goes back into herself. She can go from animated to crying about her past within the same conversation. She doesn't lead the house and is not eating regular meals. Crisp packets and alcohol bottles are all that seems to be lying around. How can someone go from a happy healthy outgoing working person to a complete drinking recluse in 2 months?
She says she won't leave the house to go to the GP as she can't get on a bus and she can't afford a taxi.
She has missed medical appointments because she apparently forgets about them.
She seems happy when I'm with her, but she lives alone and I suspect when I walk out the door she just cries.
How can I help her?
