Answer :
Carla should take some time off of the project and get back to doing some of the activities she enjoys, like reading the newspaper or taking a walk.
Carla would be better off dedicating less time to the project, so that she can dedicate more time to other things that matter to her.
If this is impossible, she can try to organize her time better. She can establish a routine that tries to include everything she wants to do. She can also prioritize the things that affect her health, as these are the ones that will have the most impact in her life. She can also try to delegate some of the duties to someone that can help her, such as a partner or a coworker.
