At some point in our lives, we all come across someone who causes many problems in our lives. They may stir up trouble and be the reason behind some conflicts. These people are toxic individuals, and their behaviour is called toxic behaviour. The toxic traits of a toxic person include unsupportive and unpleasant behaviour, being manipulative, judgmental, controlling, and self-centred. Such people can cause various negative feelings and emotions that you may be experiencing, like depression, anxiousness, worthlessness, and unhappiness.
