I can't think of another bad advice. I think most of them were described here and I also don't tell everybody about my depression...
One thing I wanted to share here.
In my home country word "depression" is pretty new.
My mom didn't have it in her generation, or at least it was not identified as some illness, it was more like a character flaw. So when I mentioned it to her, in the beginning she dismissed it, like I was just making up some fancy word to excuse my failures.
Then later, when she saw on TV a documentary that depression will kill more people in a very near future than other physical illnesses, she became concerned and now she has really changed her attitude to that. She just keeps telling me that I need to fight it. And I think it's a good advice.
If I am still alive, then I have to fight it. I get breaks sometimes. But sometimes I go few months in deep depression, causes by major events.
From last year I've been working hard to get out of that depression hole. I felt I was doing better, until I made a very bad decision - to move in with a "friend". That move dropped me right back into my depression hole and perhaps even deeper than it was before.
We have to be careful, who we let into our lives. Some people are just so evil, they wish no well to others, they want to see me fail, to see me suffer, to see me die....
