Yup. With ADHD you constantly feel behind the 8-ball, forever in a deficit of agency. Worse when it's paired with anxiety so you never feel you are in control or make the right decision. Most of your time is spent worrying about what you didn't do and what you might have missed. Some things have higher priority to worry about so "small" things like calling that ADHD doctor fall by the wayside. Inevitably the chaos catches up where you forget an important event, forget to pay a bill, etc, and you're in panic emergency mode trying to fix it. So of course you forget to call that ADHD specialist. All day every day is like this.
