what do you do if your dh is possibly on the verge of a breakdown?

[namechangejustincase]

I think the title says it all.
dh is under increasing pressure in his job -he's a vicar and the parish and the sheer VENOM of a a lot of people in it are just wearing him down, making him unhappy....
And i just don't know what to do.

I'm sure there is more to say but I'm not sure what.

it doesn't help that i'm not in a great place emotionally -always had battles with depression, and having had 2 miscarriages this year, am in a vulnerable place but trying to be so strong.... But this isn't about me - although I just want to curl up and cry about the whole lot

oh goodness. Almost a year to the day and it's all happening again.
We now have a baby ds too which is causing lots of stress. I don't know what to say except - waaaah I can't cope with dh not coping.
