I think it is, yes. It is part of being able to step away and not let things that used to be triggers no longer upset us. It is part of being the bigger person even though we might feel like the patsy. I believe in the end it helps us to develop a more balanced personality and more flexibility to deal with all those nasty things life gives us. It gives us practise in just... letting things go. I don't know about others but part of my depression stems from caring too much. So it is part of my healing (when I am able to do it) that I pick and choose what I care about. I have to build a mental shell against a lot of stuff or it pulls me down.
