Leaning on is a phrase used to describe a person who relies heavily on someone or something for support or guidance. There are several synonyms for this phrase, including depending on, relying on, counting on, and trusting in. Each of these terms conveys a sense of vulnerability, as the person in question is putting their faith in someone or something outside of themselves. In some cases, leaning on someone or something may be seen as a weakness, while in others it is a sign of strength and resilience. Ultimately, the choice to rely on others or oneself is a personal one, with both options carrying their own set of risks and rewards.
