Can you see that what your parents are saying is actually very hopeful.
I know my H found it very hard to be with me when I was depressed - living with someone who is suffering from depression is not easy. I think your parents are daed on about saying you need to work on you. That's what saved my M - my H saw the changes. He complicated it by having an A as he was so miserable but basically he was willing to turn back to me because he saw how hard I was trying to change.
Has your W spoken to your parents much about how she feels?
Dig deep and do this.
BTW are you a fellow Brit?
