Forget trying to get support from his family unless they are already leaning that way. I had a great relationship with my SILs for 33 years and then when H and I separated, it felt like I had never existed. They aren't angry with me, they just became silent.
Oh, and my H told my 84 yr old MIL one time that I kicked him out. I didn't kick him out, I asked him to leave after he dropped the bomb. Another time he told her that he got tired of sleeping on the couch. He slept on the couch one night in 33yrs. Give me a break. What he left out of the story to his mother was the part where he said, "I'm done, I don't love you any more, I haven't loved you for a long time and I don't think I can ever love you again." They tell the story that makes them feel better about themselves.
I'm always saddened when people with depression are treated differently than those with other illnesses. If you have cancer people rally around you, support you, tell you how strong you are to fight the good fight, etc. Depression, people don't even want to talk about it, it still has a stigma attached.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
