Thanks @faraday and @Auspice . That is a helpful explanation.
But now I'm more confused, lol. I rarely miss deadlines, but that's because I tend to cram at the very last minute. Maybe I have mild ADHD? Talking about this is really weird because, like... some of the stuff is me to a T. All the time. Messy (more like absolute disaster) of a room, papers always everywhere, scattered, disorganized, make fancy plans and never go through with them, always forget to send thank you cards, bills pile up, etc...
But, like, at work? I'm fine at work. I mean, I get distracted constantly, but I get shit done on time, even though deadlines are really stressful. I don't know if this means I just have a mild form of the disorder or if being undiagnosed for 30 years means I developed coping strategies that let me function albeit miserably.
It is also 5 in the morning and I have spent the past hour and a half to two hours looking at ancient churches in England. So... there's definitely some executive function issues going on.
BUT LOOK AT THIS CHURCH
