Thanks echoes. That is the way I have been looking at it, too. Especially as I have just heard about how my Dad used to behave - which I was unaware about - which to me would be classic BPD. So the family link appears to be there too.

Many thanks for your comments. They are much appreciated. I have just been to see the conslutant psychotherapist today - and they don't seem to keen to diagnose, but rather keep trying treatments til one works. I just have a strong feeling I don't have time for this approach.

Something is very wrong and I am certain that depression is just the symptom of something greater. I really think that treating just the depression will only leave me back in the same place again and again and again.
