Hey I'm new!

I was officially diagnosed with adhd last year but I've known all my life I had all the experiences people on the spectrum had, and It effected me everyday. One thing that's helped is little spirally bracelets with tags that I write stuff to do on. That way when I complete a task I can physically take off the bracelets and hear the other tasks jingling. My question is how is do y'all motivate yourself when you're stuck in "analysis paralysis"? I get that all the time where there's so many tasks to do and I'm not sure what to do first so I just do nothing. Literally nothing, I sit and stare at a wall while overthinking.
