Having a difficult person in our life, creates an environment that does not support our well-being. Around this person (or people), it is difficult to grow, flourish, to have or maintain a positive attitude, or to enjoy life. In other words, to our well-being, this person is toxic. As I just mentioned, this could be a family member, coworker, boss, neighbor, ex-lover, etc. It could even be a collection of people such as a toxic work environment.
