It's true that you'll always have your problems with you. It's also true that "wherever you go, there you are." But for every set of problems S₁ ... there's a secondary set S₂ that consists basically of "thinking too damn much about S₁" along with a heaping portion of "why me, why me, why me?". The growth of which starts to take on a life of its own, and to greatly leverage the suffering that S₁ would otherwise cause on its own. So part of the basic healing mechanism of the change-of-coordinates approach is that, while it doesn't reduce the size of S₁ directly ... it does help reduce the run-away swelling of S₂ very substantially. Which allows slow-acting but powerful natural healing factors (the passage of time, as a sibling commenter point out) to focus much better on S₁. Until one day, you're going about your business ... and you realize you haven't thought about S₁ in a while. Not just for a couple of hours, but for a like a full day or more. That's when you start to realize that it's at least possible to move on.
