An upset toxic person wants others to feel upset as well
If there is a toxic person who feels sad and upset, you can be sure that you as well as all others around will feel sad and upset as well. Toxic people do not want others feel good when they are unhappy. The environment becomes toxic, too. It is impossible to feel good since the atmosphere around a sad toxic individual will always be negative. Be careful in such situations because if you have plans, then those plans can be ruined and destroyed by a toxic person.

High levels of secret insecurity
Toxic people are insecure. Their toxicity is a way to protect themselves from possible attacks. They attack other people first before anyone else tries to attack and hurt them. Toxic people are very sensitive to criticism. They may lie to you and say that they are indifferent to other people’s opinions, but they love to be approved and supported. If someone thinks they are not good enough, they suffer and feel sad. They usually hide their true feelings and emotions. When they open up, you can see how insecure they are.
