This describes me as well. Bipolar and ADHD. If I'm engaged in something I obsess over it and work 10+ hours until it's done.
It takes every other feeling away and not until I stop do other things come back (sleep fatigue, hunger, etc)
Yes, just that. I struggle a lot with getting engaged. Especially if I'm uncertain how to proceed. Or if whatever seems too difficult. Too big to imagine.
But once I do get engaged, especially if I understand (or at least, think I do) how to proceed, I won't stop until it's done.
