I Have Toxic Family Members

I'm starting to believe my mom is one of these toxic people, she will complain about everything from her health, body, people, etc. and when I try to bring reason into the discussion, she refuses to listen and continues on with her rants. It has caused me much stress over the years. It's disheartening that no matter how hard you try there are some people you just can't help/ reason with. That's just the way they are.
