I've just found out that the father of a friend of mine is in hospital receiving treatment for a mental illness. I have always been very very close to her parents. I would like to send a card to her mother and also a card to her father. I am unsure of what to write in the cards. Please can anyone offer me any advice - if you have received such cards, what words did you find comforting in any way or is it ok just to write that I am thinking of you (to her mother?). What would you advise I write to her father? Thank you very much.
