Lost my mom today

She blocked me after I quoted a philosopher who said "where law ends, tyranny begins". It's also on the DOJ building. yesterday trump ended the rule of law by saying he and the attorney general decide what the law is. My mom said "I don't have to have a relationship with you" and blocked me. Honestly, I felt relieved. She is mentally unstable, but refuses all help and does not seek treatment. For her to voluntarily sever ties actually is freeing as about once a year she has an episode and runs away and threatens to kill herself. Am I a bad person for being exhausted and relieved to not talk with her anymore?
