This may not appeal to everyone, but I have just got a book, written by Matt Haig, I heard an interview, with him on the radio, he was talking about this book, which he wrote some years ago.
It's called " REASONS TO STAY ALIVE " , it's about the depression he had and how he dealt with it and came out the other side.
I really felt, that I had to read this book, as the grief that we are all experiencing, can quite easily turn to depression, without us even knowing.
