My depression went a way months ago. I haven't thought once about suicide, giving up, ... since then. Unfortunately, some of my family members are still mentally ill...
I want to help out my father, but he gets angry easily, and while he agrees with me on some things now (took me a while to convince him), he will never eat paleo. His parents lived pretty much on grains, you see. And he loves his parents.
Since he retired he never has things to do and feels down all the time. He doesn't say it, but it's very clear. Our house is small, and my mother is kinda sad because she finds it hard to be around someone who's sad all the time. She cut out sugar a long time ago and cured her mental (mood) problems that way, so she doesn't like it when people give up or do nothing.
It's clear that he starts ditching his friends one by one. I'm afraid that, because it's harder for older persons to make new friends, he will ruin his own life slowly.
But what can I do? He doesn't like the way I eat at all (he has cholesterol issues and still thinks eggs, butter and meat caused it), so he will never do those kind of changes. He doesn't really like fish. He almost fainted when I said I only ate meat for a month. Basically he won't change his diet...
