over time, the physical and mental effects can be toxic.
Want better self-esteem or self-worth. Self-esteem is based on what you do (while self-worth is more about who you are). You may crave either or both, which is why you may set out to help others and neglect yourself. While wanting to feel a sense of self-worth or self-esteem isn’t necessarily a negative thing, it can become damaging to you or others.
People with megalomania can set out to help people (and have a messiah complex), too. A person with megalomania has an exaggerated sense of self-worth – they think they’re more important than they actually are. (This is different from narcissism because narcissists have an inflated sense of self-love and need for attention and admiration.) In some cases, people with a messiah complex may have megalomania, which is part of delusional disorder.
