Answer:
A teenager with a low self esteem does not care about themself or does not value their life and body.
Step-by-step explanation:
They may deem themself as unworthy of care and love and ,for example engage in unsafe, unprotected sex as they do not value themselves enough to demand safety and protection during intercourse.
They may start using substances and drugs to make themselves feel better and as a result become addicted.
They could even engage in self harm which could lead to death or injuries.
