"I can't eat from the stress getting to my stomach, and I can't sleep because I always think about the project"
I think you should take it as a rule of life that this is an unacceptable state to be in. You should see this as justification for drastic action - be it letting your team down, or standing up and saying you can't do this, or quitting entirely and moving to the equator, or whatever works for you.
I think there's no state in which it's reasonable for a human to be mentally oppressed like that, and you should do absolutely whatever it takes to get out of that situation as soon as possible and to not edge back into it. (Not to be confused with having a lot of work to do and having to work late and being under pressure from timelines. That doesn't have to necessarily come with these physiological effects.)
