People who make me feel like crap or worse off then when I encountered them consistently are written off and out of my life
Doesn’t matter if its family, nobody is entitled to your attention and suffering and it does nobody any real good for you to succumb to the inevitable dysfunction it creates in your life and relationships and also material conditions.
Don’t make excuses. If you fucked up admit it and make a plan to prevent it from happening in the future. Excuses themselves do nothing to help a situation.
