After I was diagnosed, I think it made it easier for me to be more forgiving of myself. Because I looked at my past differently because of it. So many things made more sense. The hypermobility (I could bend my legs far beyond what was normal when I was a kid and this is common in ADHD), feeling antsy/uncomfortable sitting still or otherwise not having anything to do, so many hobbies I went full force into until I got burned out or bored and moved on, impulsivity, feeling like you dont think like most people do, hyperfocus, skipping homework and other boring/tedious tasks, difficulty "shutting off your mind" to sleep, rejection sensitivity, feeling like your emotions are stronger or harder to control, rumination (agonizing over mistakes or social screw ups late at night), procrastination combined with extreme last minute productivity, sensory sensitivity eg. food textures, surfaces, socks etc, rambling, connecting completely disperate things/concepts together
