Stop maintaining relationships with people that make you feel guilty about things that you like, that make you feel awful about yourself, that put you down, that don't support you, that are mean to you.
Just kinda of fizzle out of the contact. Let it be like almost as if it might be growing apart. Just get rid of those people, because instead of just maintaining these 'relationships' with people for the sake of being polite or civil, you can be civil without having people that you can't stand in your life and you'll be so much happier.
You need to stop maintaining relationships with toxic people because it's just not good for you, your health, your happiness, and it's not worth any of your time.
