> I actually sort of resent the comparison between "why don't you just cheer up?" and "oh, just lose weight." Everyone understands that weight loss is diet and exercise, even if they've never have to do it. Most people don't understand that depression isn't just an extra long bit of being bummed out, let alone the resources a person might need to overcome depression.
> I am empathetic, what I am NOT is sympathetic. I have a problem, and I need to fix it.
That's a healthy outlook for you to have. It's the one I have, too. The people we need to have sympathy/empathy for, though, are the people who haven't gotten there yet. I imagine there was a time for you where you hadn't reached the point of understanding your problem, for any of the various reasons of shame, denial, anger, blaming others, etc.
There are a lot of people in that boat. What I think commenters here don't understand isn't that weight loss is relatively straightforward, it's that straightforward things aren't always easy, and that preparing oneself to do something difficult is hard, even if that difficult thing has clear steps to take.
Given that other people have pointed out the same vagueness in my comparison to depression, maybe it wasn't the best one to make. I will think on a different one for next time. I do think that, given the above, it makes my point though.
