This is a challenge, especially if the person is someone in your family or someone you cannot avoid being around. My advice is: if you cannot remove these people from your life because you will see them constantly, simply remove them from your heart and your tongue. Do not engage with them in petty conversations and discussions. Do not cling to delusions that you may be able to change them because toxic people at their core, are judgmental, insensitive, rude and self-centered and they cannot be reasoned with. Just let go. Do not engage. You deserve better than having to walk on eggshells around ANYONE. Be you and if someone doesn’t like it, that’s their problem, not yours.
