What does it mean to be toxic?

A person that has been labeled as "toxic" exhibits bad behaviors that hurt others or impact them negatively. They are good at manipulating people for their own self-interests.

Many people who behave in a toxic way have experienced trauma themselves or been exposed to a toxic relationship . Instead of addressing their issues in a healthy manner, they start showing toxic traits.

Toxic people don’t know how to deal with the internal stress in a normal and functional way, so they become unpleasant, inflicting the pain they have been subjected to onto others.
