I have driven up to 6 hours at a time, but I'm in hyper-focus mode the whole time and it takes everything I have to stay locked into that focus so I don't die. I think all the time about moving somewhere where I don't need a car. I hate driving and always have.
I recently found out I have ADHD. I haven't tried meds yet (but am having my first meeting with someone tomorrow to explore it as an option). I'm wondering if this will make driving more tolerable for me. It wasn't even something I thought about before this thread.
