The best way to deal with toxic people is to keep your emotions in check, and make sure you don't take things personally. When you're dealing with a toxic person, know that: Toxic people often want to make you angry, so don't give them the chance to put you in that state. You know better than to allow the unkind treatment of a toxic person make you unkind. Don't let them get away with undermining you—you deserve better than that. So, find a better way to pass your message across and leave that space as quickly as possible. Keep your boundaries clear! Know that most of the time, a toxic person acts out of desperation, frustration which is always their best option, because they feel there's no other choice. Try not to take it personally, and move on.
