When I realised that all I was thinking of was ways to end my life, I then went to the doctor, and it was just knowing that I was doing something about it and realising I was doing it because I didn't really want to die that helped.
Accept what they give you, and yes, find things you enjoy doing. I love the idea of sleeping with a happy momento, tell yourself there wil be happy times in the future also, because there will be, I'm sure of it. Some people have an easy care free life, I seem to be one of the people who lives in peaks or troughs, when I'm in a trough I try and tell myself there will be a peak at some point.
