@chris While all this *is* good advice, I wish articles like this also made sure to address the fact that you don't *have* to maintain relations with people who have such a huge negative effect on you no matter the blood relations.
I know a ton of people actually can't cut ties with relatives or other folks for many reasons, but there is a whole "you should endure your abusive/bigoted relatives no matter what, because they are family" notion that is perpetuated, that is extremely harmful.
It's good to have coping mechanisms, but I'm not a fan of the " we ask the experts how to avoid falling out with your nearest and dearest" and "Appreciate that these moments of anger, hurt, disconnection or isolation are common in family relationships" angle. The latter especially lacks nuance, there's a difference between the loneliness you feel among relatives who don't quite get you and family that is toxic. If people affect your anxiety and your mental health so negatively you need literal panic attack coping mechanisms, journaling, breathing techniques, and therapy to deal interacting with them, they are neither near nor dear to you.
