I have found that life most certainly does not get better, but my capacity to deal with the horrors of life does increase to a point I am mentally better off even now even though my life is worse than it was and is destined to continue to decline.
I feel that I will be up to the challenge and will be capable of living out my life just in a mildly depressed and somewhat cynical state. There is no passion to my unhappiness any more.
This is a sort of wisdom you acquire that can be mistaken for it "getting better".
