Yes, perfectionism can kill you, if long-term it drives you as it appears it does you. Having to have things "just so" is founded in needing control and/or demanding parents/environment. It's one thing if you're a nuclear physicist at work, and another if your just making a bed. The stress you place upon yourself, with irrational expectations wears a body down.

It's important to learn how to let things be "good enough" as a real perfectionist will never attain her goal.
