I have been with DH for 14 years and I have suspected depression for most of that time. He is always miserable, prone to intense mood swings and is generally very difficult to be around. The DC and I tiptoe around him as we are never sure what type of mood he is in and whether or not it's "safe" to be relaxed.
The kicker is that he refuses to accept that he has depression and he said once that, even if he were depressed, it's not something he would go to the doctor about because depression "is not real" and he would just need to "get over it". 
Has anyone lived in similar circumstances? If so, how do/did you manage? It is exhausting and soul destroying trying to guess his moods and act accordingly, especially when I know there is no end in sight because he refuses to get help. In the last 14 years I have turned into a nervous wreck and I need to find better ways of dealing with it.
TIA.
