Ask HN: I've quit six systems for tracking my illness. What works?

Hey everyone, I am a 20 year old college student who was recently diagnosed with seronegative spondyloarthropathy. Over the last 3 years, Ive tried apps, paper journal, Google Sheets, and notes to track/catalogue my journey. I always ended up quitting within 2-4 weeks and not keeping accurate track. Is this a common experience or do I just have to be better at tracking? Is there a unique/non habit-building way to track/catalogue/recall? Im building something for this (part of the reason why I am asking) - and if anyone is open to a longer conversation, Ill gladly pay for you time!
