Sometimes to get better, things have to get worse first. Just because something makes you focus on how bad you feel doesn't mean it can't be productive in the longer run. Though I suppose if you're depression is so severe that that extra focus might tip you over the precipice, I can see why you might not want to risk it.
I am curious to know what "Actually curing the depression" required for you?
The way I find myself most commonly experiencing meta-suffering is not when one big bad thing happens in my life, but when a lot of small frustrating things happen all within a few days. The stress becomes immense, and I think I must be anticipating more things going wrong and on some level it feels more like the universe is conspiring against me, for lack of a more scientific term.
