not sure if anyone has recommended this yet but i would highly recommend meditation i use a product called muse its a bit pricey but it has been the best tool in my toolbelt for clearing out a foggy mind and getting some clarity in my thoughts it comes with a headband that ties to an app on your phone and increasesdecreases an audible noise to let you know if you are distracted or not   ive always been skeptical of meditation until i tried this once i got used to it  i realized that ive been meditating wrong all this time i now try to meditate at least once a day for at least 10 minutes and have noticed huge difference especially with projects that im stuck on because i cant figure out how to start or plan out   hope this helps you i was diagnosed later in life and have had a lot of issues re-learning all the correct ways to do things and i found this helped the most to clear my head
