Angelica44,
Morning, has she got any close friends that can help in the short term? Anyone that live close to her? Can you call them and get them to help! She really needs professional help and as soon as you can, it’s not something you can do personally because she is probably to familiar with you approach. Do you know which GP practice she is at? She needs to go and visit them or get a call arranged to her house or mobile. If she has a friend that is closer than you can you get them to talk to her and get to her doctors as soon as she can and get help. The only way to fight it is to get some support. I’m sorry for her and you but she needs as much physical and mental support as she can get at this time and she probably won’t do it on her own in this dark time.
