Q: How do you move forward in this situation
A: there's as many ways as you need, but the real important question is 'why'. And if you've tried everything else: ('switching things', 'doing other things', 'doing shorter things so you never reach this point', 'doing no things', etc every other alternative to what you're doing now) enough times to be sure that all those options are worse, then that could be a reason you'd feel invested in following through on the current one
