Struggling with ADHD/ADD Diagnosis as a Teen

hey! i was in a similar situation- my parents didn't believe me bc i have more daydreamy/hyperfocus issues than being high-energy. body doubling helps me a lot! basically just asking someone to be in the room as you do work. even having someone on the phone with me helps. let yourself take breaks and engage in hyperfixations to relax. if possible, explain to your teachers that you're struggling with focus and achieving goals (or flat out say you think you have adhd, if you feel comfortable with that) and ask for help to make a plan! tricking yourself into doing things that are difficult with executive dysfunction also helps; each step along the way, tell yourself you aren't actually going to do xyz, you're doing something else! so like "im not getting in the shower, im just hanging up my towel. im not getting in the shower, im just taking off my clothes. im not getting in the shower, im just turning on the water." and then muscle memory takes over and whoa!! howd i get in the shower!!
