I find myself going back to a lot of the music I latched to as a teenager and listening to all of them on repeat when I get in a certain mood. Not because they're objectively good music (in fact, most is simple/juvenile), but because they're linked to specific feelings I had at that age, and are some of the few things that still make me feel young, despite me being relatively young still.
Problems at this stage in my life are so complex, multifaceted, and require long-term solutions…you get to a point where you're pushing so hard against the challenges in meeting your goals for so long that you go on autopilot, and the pains that go with it become just a dull ache. The beauty in youthful "tragedies" (first relationships/breakups, friends leaving for college, falling-out with friends, not knowing what you want to do with your life) are that because they're the first time you've encountered these problems, every wound is fresh, every one is an acute pain that throbs, and feels like it'll never end, until it does.
These same aches & pains now are a thousand scratches against a steady, calloused hand pushing back. It's still painful, but well-worn and heavy.
