The opposite of self-supported can be described in many words, but some of the most commonly used antonyms include dependent, reliant, needy, and vulnerable. These words suggest a state of being that is the complete opposite of self-supported, where a person or system relies on external factors for support and stability. Unlike self-supported, which connotes strength and independence, dependent implies a person or organization that requires constant assistance or care from others. Reliant, on the other hand, suggests an association with something or someone outside oneself for survival. Needy implies a shortage or lack of resources, while vulnerable suggests a susceptibility to harm or danger.
