money worries

Mum's been a bit worrying recently: we had a conversation where her personal wealth veered from £20,000 down to £200 within a couple of sentences. She kept stopping and saying: "no...let's see..." and sounding like she was covering up. I think that she wants to present a competent front to me so that I don't get stressed, but she just can't manage it. I was concerned that she said she was still getting "handouts" from her Solicitor, 8 months after Dad died, when I thought everything was done and dusted, so I suggested that I rang S to ask for some sort of account of how Mum stood. She was adamant that I shouldn't ring S. As Executor, though, I felt I should talk to her. S said that Mum has been in to see her every single day asking questions.... often the same ones over and over.
