I have to constantly fight the struggle OP is describing, and one thing I’ve never tried is being upfront and honest about my shortcomings… I just get upset with myself and start writing post it notes about doing better, actions to take, and sticking them all over the place. I can’t even imagine the world where I share this about myself and it’s well received by people who, at the core, just want me to deliver a very steady stream of work they can plan for.

You don't always need to announce it to everyone. You can try talking to HR and asking for accommodations (which someone with ADHD is eligible for through the ADA). And the nice thing there is you don't have to tell anyone else.

Accommodations can include things as simple as leeway for coming in late, or with deadlines. They can even go up to removing specific requirements from your role.

It's worth asking what's available at least.
