I started some ADHD medication today. I have been able to see distractions and just not engage. I've got a bunch of things done. I've been able to cleanly focus blocks of time that I'd drift away otherwise. I do not have music in my head for the first time in *many many years*. I can stop and breathe.
I have absolutely no idea what would or could work for you, but your comment resonated with me and I wanted to help share something that feels like a big change for me personally and hopefully others. I waited decades to ask a professional and I absolutely should not have done that.
