Thanks Sally you are a sweetie and so kind.
I just hate the feeling of being helpless and not knowing what best to do for my friend and at such a difficult time in her life.
Just found a card which has the wording already on it and as one or two of you have suggested.
I am going now to post off in a minute or two.

I now things are difficult for you right at the moment ...
... I'm thinking of you

and inside it reads

and want you to know you
can alway rely on me for a
hug, or shoulder to cry on.
I'm there for you whenever
you need me.
Take care

Love and best wishes from Debbie
