I have the same issue, and I haven’t found any good solutions either. Todoist worked for a short while, but I quickly realized that a task manager with no calendar is almost useless to me. I’d love to hear others’ systems.
Edit: I know Todoist can sync with Google Calendar, but that’s an extra app and a Google account on top. I won’t be renewing my subscription when this one runs out.
I honestly feel for your friend and hope she gets the help she needs, but I also don’t necessarily disagree with what you told her, although you could have definitely used more tact. There’s been an explosion of people thinking they have ADHD because of TikTok videos, and while some of them may, just because you identify with one symptom does not mean you have it. While not ALL doctors are good doctors you still need one to diagnose you. I don’t mean to sound coarse, it’s just an observation.
Disclosure: I’m an old fuck diagnosed late in life.
