cazz1975 - the issue here is that Depression is far more difficult to deal with, both for the sufferer, and for partners and friends, than a 'standard' disease.
If someone has cancer, or a broken leg, everyone has a reference pioint, knows what goes on, and can act accordingly.
Depression is far more insidious, not least because the outward signs are hidden as far as possible by the sufferer because the idea that people know about it simply adds to the feelings of alienation.
Souldarkness' partner needs to understand her illness in the terms I have described, and of course the 'pull yourself together' approach helps no-one, however frustrated he may be.
Of course the guy is entitled to feel helpless, miserable, unable to help, and all the other reactions that go with dealing with someone with this dreadful disease - but if he understands better, he will be able to accomodate her need for peace and quiet, silence, time alone, and inability to communicate meaningfully.
Part of the side-issue of Depression is fear for all concerned, the sufferer, their partner, and so on, so education can only ever help to dispel the fear for the partner, and help him understand that this condition may be there for a long time, maybe for life, and he needs to get a handle on dealing with it for the sake of their future together.
Of course it's hard, but that is no-one's fault. the reaction to avoid is that the sufferer can in some way 'pull themsevles together' - ttrust me, it's just not an option.
