This is pretty much how everyone deals with a depressed person.

"I don't know what to do with you"

Because it's the depressed person who has to get themselves better, everyone else just has to be there.

That's how it works I'm afraid.

Maybe the first time you go through depression you blame others for not making you better or loving you more but if you're 30 and still doing that you need to learn better ways of dealing with it.
