I think some people, when they don't understand what depression really is, take responsibility for it. Like, they take it personally thinking it's something they did or didn't do to make us happy. Or that there SHOULD be something they could say or do to make us feel better, and when that's not possible it upsets them. It's hard to explain to someone that sometimes it's JUST NOT POSSIBLE for you to be happy. That it's like when you unplug a lamp from the wall, the light simply WON'T come on! That's what depression is like for me. I may want to be happy, I may have reasons to be happy, but that "switch" in my head has a broken connection and I don't have the ability to be happy! I've tried explaining this to my own boyfriend but he still thinks that he could do things to make me happy. It's frustrating for both of us! I find it easier to talk to people who know what I'm going through.
