Medication helps. Lifestyle hasn't changed too much - I still have endless to-do lists, bookmarks, things I need to get to, but medication has helped me in the sense that it doesn't all feel overwhelming at every single moment, anymore. Days feel easier to manage.
lifestyle -- fitness/nutrition/meditating/prioritization, has helped 100x more than medication ever did. was on meds from age 12-20, everything under the sun, and they were net-negative for me. but that's just me. everyone is diff, with so many underlying factors to why our brains operate the way they do. just glad we have this community to discuss it. never had this when I was growing up.
