Mum diagnosed with chronic lymphocytic leukaemia

As the title says - mum was diagnosed in February of this year, after feeling unwell for a number of months which she simply put down to doing too much. 

She's losing weight but she's hardly eating anything & at the moment not quite sure what is going to happen. But she's seeing drs & etc, at the moment. 

Not quite sure why I'm writing this post but I guess it's to ask for support, comfort, because as much as I'm trying to be supportive I'm frightened. I've not read much about CMML purely because I don't want to frighten myself more.
